About Diamonds

A summary of the different properties regarding Diamonds and Jewellery

To classify or describe jewelry or diamonds, we use a specific vocabulary. Our vocabulary is regularly refined and learns us more about issues that are important in choosing the right jewel or the right diamond. Do not hesitate to ask us any additional information if you are not sure or if you do not understand something completely. We will gladly inform you further.

Diamond Shape

A diamond can take on many different shapes. The most common and popular form is undoubtedly the round cut brilliant. Additionally there are various fancy shapes: the marquise (or navette), the pear, the oval, the emerald, the princess (square) and the heart shape. The invention of modern diamond polishing is generally contributed to the Flemish jeweller, Lodewyk van Berquem (Bruges), who lived in the 15th century. Van Berken invented a polishing wheel, called the scaif, using olive oil and diamond dust. This relatively simple instrument revolutionized the diamond cutting industry. Since then, it was possible to symmetrically polish the facets of a diamond and in angles that maximized scintillation.

Round Brilliant

The modern brilliant cut diamond is without a shadow of a doubt the most popular shape available. It consists of 58 facets and the shape is optimized to reflected the light entering the stone through the top (table). The cut surfaced in the mid 17th century and counted only 17 facets in the crown. Later, a Venetian cutter called Vincent Peruzzi, improved the shape to 33 facets in the crown.

Princess

The princess cut is the second most popular diamond cut (the brilliant cut being the most popular). This cut, also referred to as a square modified brilliant, is relatively new. Unlike most square or oblong shapes, the facets are brilliant cut. Because of this, princess cut diamonds have more scintillation and fire than traditional step cut stones.

Oval

Oval cut diamonds can vary in length-to-width ratios, which can affect their appearance. A higher length-to-width ratio can make the diamond appear more elongated, while a lower ratio can make it appear more rounded. The choice of ratio ultimately depends on personal preference. Ideally, the diamond should be cut in such a way that the light entering the diamond is refracted and reflected evenly, resulting in a brilliant and sparkling appearance. Oval diamonds are also known for their ability to mask certain inclusions or flaws that may be visible in other diamond shapes. This is because their elongated shape can help to hide imperfections, making them a good choice for those who want a high-quality diamond that still fits within their budget.

Pear

The pear is a brilliant-cut diamond in the shape of a teardrop: a single point and rounded end. It’s a popular choice for a variety of jewellery, most notably pendants and earrings. By choosing an elongated pear shape, the lenght of the fingers is accentuated. For a traditional pear-shaped diamond, the length-to-width ratio should be around 1.5:1.

Baguette

Baguette-cut diamonds are a type of diamond cut that is rectangular or elongated with straight sides and step-cut facets. The name "baguette" comes from the French word for "rod" or "stick," which describes the shape of the diamond. Baguette-cut diamonds are usually used as accent stones in jewelry, particularly in engagement rings, wedding bands, and bracelets. Baguette-cut diamonds have fewer facets than round brilliant-cut diamonds, which gives them a more subdued and elegant appearance. Their elongated shape makes them well-suited for use in channel settings or side-by-side settings, where they can complement a larger center stone or add a touch of sparkle to a design.

Emerald

The emerald cut, also referred to as step cut or table cut, is a basic/fundamental cut (like the brilliant cut). Unlike the facets in the brilliant cut, the facets of the emerald are cut in steps: stripe-like facets, which run parallel to the girdle. The corners are truncated, this is done to protect the stone. Sharp edges and points are vurnerable and risk getting chipped. The emerald cut is often used in colored stones because light is better reflected and color is intensified.

Cushion

Cushion cuts were at the height of their popularity during most of the nineteenth century. The basis for the cushion-cut is the Old Mine Cut, a square cut with rounded corners, a high crown, smallish table and large facets. The modern cushion cut has a square shape consisting of 64 facets which are placed in an angle to maximize depth of the gemstone (note the difference with the modern brilliant cut, which maximizes the reflection of light towards the eye).

Marquise

The particular cut of a stone is mostly a pragmatic choice. The shape of the uncut, rough diamond gives the first indication of the most efficient cut/shape. Cutting a round stone out of an oblong rough diamond, would we very wastefull. A suitable shape for this situation is the marquise. Having roughly the same amount of facets as the brilliant cut, the marquise is more difficult to cut because of the fragile, sharp points.

Heart

Heart shaped diamonds are a popular and romantic choice for engagement rings, anniversary gifts, and other special occasions. They are a type of fancy cut diamond that is typically elongated and pointed at one end, with a curved, rounded end opposite. When choosing a heart shaped diamond, it's important to look for one with a well-proportioned cut and good symmetry to ensure that it has maximum sparkle and brilliance. Heart shaped diamonds can also vary in terms of the length-to-width ratio, which affects the overall shape and appearance of the stone. The ideal length-to-width ratio for a heart shaped diamond is usually considered to be around 1.00 to 1.10, although this is largely a matter of personal preference. Overall, heart shaped diamonds are a unique and romantic choice for anyone looking for a special and meaningful piece of jewelry.

Triangle

Triangle cut diamonds, also known as trilliant cut or trillion cut diamonds, are triangular-shaped diamonds with three equal sides and 50 or 25 facets, depending on whether the cut is a standard trilliant or a modified trilliant. They are often used as side stones in three-stone engagement rings, as well as in earrings, pendants, and other types of jewelry. The triangle cut diamond was first introduced in the Netherlands in the 1960s and has since gained popularity due to its unique and versatile appearance. The shape of the diamond can vary slightly depending on the proportions and angles of the cut, but in general, it has pointed corners and a flat top. One of the benefits of the triangle cut diamond is that it can make a smaller carat weight appear larger due to its elongated shape and large surface area. Additionally, its unique shape and brilliance can add a distinctive touch to any piece of jewelry.

Cabochons

Radiant

Radiant diamonds are a popular diamond cut that was first introduced in the 1970s. They are characterized by their square or rectangular shape with trimmed corners and a brilliant-cut facet pattern that maximizes their brilliance and fire. The term "cut-cornered rectangular modified brilliant" is often a more generic description and can refer to various styles and variations of the radiant cut design, depending on the specific cutter and their techniques. This is a more technical term used to describe the same style of cut in diamond certifications. It describes a rectangular diamond with cut corners and a brilliant-cut facet pattern. Radiant cut diamonds can vary in their length-to-width ratio, which affects their overall appearance. A length-to-width ratio of 1.00 is considered ideal for a perfectly square shape, while ratios above 1.10 can elongate the shape into a more rectangular appearance. Radiant diamonds are known for their versatility and can be set in a variety of styles, including solitaires, halos, and three-stone settings.

Square Step-Cut

Asscher

The Asscher cut is a type of diamond cut that was first developed in the early 1900s by the Asscher Brothers, who were diamond cutters in Amsterdam. It is a stepped square or rectangular cut with cropped corners, similar to an emerald cut but with larger step facets, creating a more brilliant appearance. Asscher cut diamonds are known for their unique and elegant appearance, with a distinctive "X" pattern visible from the top of the diamond. They typically have a high crown, small table, deep pavilion, and cut corners, which enhances the diamond's clarity and brilliance. Asscher cut diamonds are popular for use in engagement rings and other high-end jewelry, and they are often set in vintage-style settings. They are also known for their versatility, as they can look stunning in both modern and classic designs. When shopping for an Asscher cut diamond, it is important to consider the diamond's cut quality, as a well-cut diamond will exhibit more fire and brilliance. It is also important to look for a diamond with good clarity, as the cut of an Asscher diamond can make inclusions more visible.

Tapered Baguette

Tapered baguettes are a popular style of diamond cut that is often used as a side stone in engagement rings and other fine jewelry. As the name suggests, they are elongated, rectangular-shaped diamonds that taper towards the end, creating a beautiful, tapered effect. The cut typically features 14 facets and can come in a range of sizes, colors, and clarity grades. Tapered baguettes are often used to complement larger center stones, such as round or princess-cut diamonds, as they add a touch of elegance and sophistication to the overall design. They can also be used as the main stone in a piece of jewelry, such as in a pair of diamond stud earrings or a delicate pendant. One of the advantages of tapered baguettes is that they are incredibly versatile and can be set in a variety of different ways, including channel, bar, and claw settings. This allows jewelers and designers to create a range of different styles and designs that can suit a wide range of tastes and budgets. Overall, tapered baguettes are a timeless and classic choice for those looking to add a touch of sparkle and sophistication to their jewelry collection.

Clarity

Diamonds are formed under extreme physical conditions and because of this, no diamond is free of imperfections. These imperfections can impede the passing of light through the diamond and therefore lessen the brightness of a stone. However, minor inclusions can be useful since they can contribute to the unique character of a diamond. Flaws are examined by experts under 10x magnification and can be divided under tzo categories: internal characteristics or inclusions and external characteristics or blemishes.

FL - Flawless

No inclusions or blemishes are visible to a skilled grader using 10× magnification. And without minor surface blemishes, such as small scratches or extra facets.

IF - Internally Flawless

IF diamonds are free from internal characteristics/inclusions when examined under 10x magnification. A diamond is not disqualified from the Loupe Clean grade if internal graining is not reflective, white or coloured and does not significantly affect transparency.

VVS1 - Very, Very Slightly Included 1

VVS1 diamonds contain minute internal characteristics/inclusions. These are extremely difficult to observe when examined under 10x magnification.

VVS2 - very, Very Slightly Included 2

VVS2 diamonds contain minute internal characteristics/inclusions which are very difficult to observe when examined under 10x magnification.

VS1 - Very Slightly Included 1

VS1 diamonds contain minor internal characteristics/inclusions which are difficult to observe when examined under 10x magnification.

VS2 - very Slightly Included 2

VS2 diamonds contain minor internal characteristics/inclusions which are somewhat easy to observe under 10x magnification.

SI1 - Slightly Included 1

SI1 diamonds contain noticeable internal characteristics/inclusions which are easy to observe when examined under 10x magnification.

SI2 - Slightly Included 2

SI2 diamonds contain noticeable internal characteristics/inclusions which are very easy to observe when examined under 10x magnification.

I1 - Included 1

I1/P1 diamonds contain internal characteristics/inclusions which are prominent when examined under 10x magnification. They are also visible face up to the unaided eye. Under certain circumstances, internal characteristics/inclusions may also be visible face up to the unaided eye in higher grades. These diamonds can also be calleD Piqué 1.

I2 - Included 2

I2/P2 diamonds shall contain internal characteristics/inclusions which are very prominent when examined under 10x magnification. They are also easily visible face up to the unaided eye, slightly reducing the brilliancy of the diamond. These diamonds are also called Piqué 2.

I3 - Included 3

I3/P3 diamonds contain internal characteristics/inclusions which are extremely prominent when examined under 10x magnification. They are also very easily visible face up to the unaided eye, reducing the brilliancy of the diamond. These diamonds are can also be called Piqué 3.

Colour

In the context of diamonds, colour is something the buyer does not want to see. The less visible the colour, the higher the value of the diamond; although the opposite is true for fancy-colour diamonds. The most common grading system used, is that of GIA. Using a colour-system ranging from the letter D (100% colourless) to the letter Z (near-colourless), this scale defines a well defined spectrum of all possible colours within a diamond. The difference between colours are often very subtle and usually not visible to the untrained eye. It will however have a significant impact on the pricing of the stone. Although the most common grading system used is that of GIA, there are different organizations that also grade diamonds, such as: the American Gem Society (AGS) which uses the electric calorimeter, the International Diamond Council (IDC) and Scandinavian Diamond Nomenclature (Scan D.N). To be complete, we have also listed the different gradings systems as well.

D - Colourless/ Exceptional White+

This is the highest color grade a diamond may recieve, the diamond is then 100% colorless. These diamonds are extremely rare and also heavily priced. An alternative name used for this colour is 'River' in Scan. D.N and has a value of 0-0,49 on the electronic calorimeter.

E -Colourless/ Exceptional White

E colour diamonds are very bright and white. They display virtually no color. Its alternative name in Scan. D.N is also 'River' and has a value of 0,5-0,99 on the electronic calorimeter.

F - Colourless/ Rare White+

These are exceptionally transparent and also very rare and highly priced. It is very difficult to find traces of color in E or F graded diamonds, especially to the untrained eye. In Scan. D.N. This color is called Top Wesselton and has a value of 1,00-1,49 on the electronic calorimeter.

G - Near Colourless/ Rare White

Only when these diamonds are held next to a master stone of higher color grade, can a slight color be detected. Otherwise color is nealry indiscernible. Although these diamonds are still rare, they are slightly less expensive and are considered a good value. In Scan. D.N. G diamonds are called Top Wesselton and has a value of 1,5-1,99 on the electronic caloriemeter.

H - Near Colourless/ White

H diamonds contains noticeable colour only when it is being compared to higher color diamonds. These diamonds are considered a good value. In Scan. D.N. These diamonds are called Wesselton and have a value of 2,0-2,49 on the electronic calorimeter.

I-Near Colourless/ Slightly Tinted White+

Slight color in these diamonds are detectable. However, once the diamond is mounted, the color is unnoticeable to the untrained eye. The majority of these diamonds are used for engagement rings, earrings and pendants, due to it's good value. In Scan. D.N. they are called Top Crystal and have a value of 2,5-2,99 on the electronic calorimeter.

J -Near Colourless/ Slightly Tinted White

J diamonds have a slightly noticeable color but still appears colourless to the untrained eye. In Scan. D.N. they are called Crystal and have a value of 3,0-3,49 on the electronic calorimeter.

K -Faint yellow/ Tinted White+

K diamonds have a yellow tint that is more easily detected by the untrained eye. Due to its noticeable color, the price of a K diamond is often half the price of a G diamond. In Scan. D.N. the diamond is called Top Cape and has a value of 3,5-3,99 on the electronic calorimeter.

fluorescence

Fluorescence is the emission of visible light by a diamond when it is stimulated by invisible ultraviolet (UV) rays. It is a common characteristic of diamonds. The diamond simply glows under the UV lights, usually a blue color, which most often stops when the energy source causing it is removed.

nil

"Nil fluorescence" refers to the absence of fluorescence in the gemstone. Fluorescence is a phenomenon where a material emits visible light when exposed to ultraviolet (UV) light. In the case of diamonds, they can emit a visible glow under UV light due to the presence of certain impurities or structural defects in the crystal lattice. Nil fluorescence in a diamond means that the stone does not fluoresce at all or exhibits a negligible fluorescence response under UV light. This characteristic is neither considered good nor bad, as fluorescence does not significantly affect a diamond's brilliance or sparkle in normal lighting conditions. Diamond fluorescence is a subjective preference, and some people prefer diamonds with no fluorescence as they believe it makes the stone appear more "pure" or colorless.

very slight

Zeer lichte fluorescentie in een diamant verwijst naar een nauwelijks waarneembare fluorescentiereactie wanneer de steen wordt blootgesteld aan ultraviolet (UV) licht. Het Gemological Institute of America (GIA) beoordeelt diamantfluorescentie op een schaal die vijf categorieën omvat: geen, zwak, medium, sterk en zeer sterk. "Zeer lichte fluorescentie" valt onder de categorie "Zwak", wat het op een na mildste niveau van fluorescentie is. Wanneer een diamant een zeer lichte fluorescentie heeft, is de zichtbare gloed die hij afgeeft onder UV-licht minimaal en nauwelijks waarneembaar onder normale lichtomstandigheden. In veel gevallen heeft dit niveau van fluorescentie weinig tot geen invloed op het uiterlijk van de diamant met het blote oog. In feite worden de meeste diamanten met zwakke fluorescentie als volkomen normaal beschouwd en worden ze niet geacht een negatieve invloed te hebben op de schoonheid of waarde van de steen. In sommige gevallen kan zeer lichte fluorescentie zelfs voordelig zijn. Dit is waarom: Verbeterde kleurweergave: Diamanten met een zwakke fluorescentie kunnen bij daglicht iets witter of kleurlozer lijken. Dit komt omdat de fluorescentie de vage gele tint die in sommige diamanten aanwezig kan zijn, kan tegengaan, waardoor ze helderder lijken. Kostenbesparing: Diamanten met zwakke fluorescentie zijn vaak iets lager geprijsd dan vergelijkbare stenen zonder fluorescentie. Kiezen voor een diamant met zeer lichte fluorescentie kan daarom een budgetvriendelijke keuze zijn zonder in te leveren op schoonheid. Unieke kenmerken: sommige mensen waarderen de subtiele gloed die zwakke fluorescentie aan de diamant geeft. Het kan een onderscheidende toets aan de steen geven, waardoor deze zich onderscheidt van diamanten zonder fluorescentie. Het is echter essentieel om te onthouden dat de impact van fluorescentie op het uiterlijk van een diamant subjectief is en varieert van persoon tot persoon. Terwijl sommige mensen de voorkeur geven aan diamanten met een zeer lichte fluorescentie, geven anderen misschien de voorkeur aan stenen zonder fluorescentie. Zoals bij elke aankoop van diamant, is het van cruciaal belang om de steen als geheel te evalueren, rekening houdend met de slijpvorm, kleur, helderheid en karaatgewicht, naast het niveau van fluorescentie, om de algehele schoonheid en waarde te bepalen.

slight

Fluorescence in diamonds refers to the emission of visible light when the diamond is exposed to ultraviolet (UV) light. It can be blue, yellow, or other colors. Around 25% to 35% of diamonds exhibit some degree of fluorescence. A slight fluorescence is typically considered to be in the lower range of the scale, and it is generally less noticeable than medium or strong fluorescence. In most cases, slight fluorescence does not have a significant impact on a diamond's appearance. In fact, some people find that a slight blue fluorescence can make a diamond appear whiter, especially in natural daylight or under UV light. However, keep in mind that the impact of fluorescence on a diamond's appearance is subjective, and individual preferences may vary. The effect of fluorescence on a diamond's appearance is subjective. If you are considering purchasing a diamond with slight fluorescence, it's essential to view the diamond in person and see how you feel about its appearance.

faint

strong

In natural diamonds fluorescence typically causes a faint bluish light to emit from the diamond. This bluish light can nicely improve the look of a diamond in the H to K color range. That’s because the blue tone diminishes the yellow hue that start to appear in diamonds in this range of the color scale. However, if a diamond is a D, E or F color and the fluorescence is strong, it may be detrimental to the appearance of the stone, creating a hazy dullness, sometimes described as milky. UV must be present to excite fluorescence, so without a UV source there is no impact. Daylight has UV, but very slight fluorescence is still hard to detect on a sunny day. Slight may possibly be seen. Strong fluorescence is rare but it’s typically observable in daylight. If you know that a stone has fluorescence, look at it under different light sources to see how the diamond changes. Fluorescence lasts only as long as the diamond is exposed to UV light, so the stone changes according to the light. The same stone may look different when viewed in different light. The diamond should stay bright and glowing under any light source. Before deciding that a diamond with fluorescence is not for you, examine it carefully, because it may actually be just the stone for you. A lower color that looks brighter and whiter than its equivalent counterparts at a more attractive price.

Cut

The exceptional brilliance and visual appeal of diamonds is, above all, the result of the cut: the relationship between the various components of a stone (the dimensions of and the angles between the facets), the symmetry of a stone and its polish. Cut should not be confused with the shape of a diamond (the silhouette seen from the top).

Ideal

3 x Excellent

Excellent

Tablesize between 54 and 62%, Crown height between 12 and 16%, Pavilion depth between 43 and 44.5%

Very Good

Tablesize between 52 and 53% or between 63 and 66%, Crown height between 11 and 11.5% or between 16.5 and 18%, Pavilion depth between 41.5 and 42.5% or 45%

Good

Tablesize between 50 and 51% and between 67 and 70%, Crown height between 9% and 10.5% or between 18.5 and 19.5%, Pavilion depth between 40 and 41% and between 45.5 and 46.5%

Fair

Tablesize up to 49% and upward of 71%, Crown height up to 8.5% and upward of 20%, Pavilion depth up to 39.5% and upward of 47%

Poor

A poor cut grade is assigned when either polish or symmetry is poor.

Fancy Colour

Fancy Color diamonds are valued using different criteria than those used for regular diamonds. When the color is rare, the more intensely colored a diamond is, the more valuable it becomes. Another factor that affects the value of Fancy-Colored diamonds is fashion trends. For example, pink diamonds fetched higher prices after Jennifer Lopez received a pink diamond engagement ring. Extremely low grade quality has not stopped creative merchants from marketing for example Dark Brown diamonds as so-called chocolate diamonds. Fancy-colored diamonds such as the deep blue Hope Diamond are among the most valuable and sought-after diamonds in the world.

Yellow

Fancy yellow diamonds are a type of colored diamond, which are prized for their beautiful and unique hues. Yellow diamonds get their color from the presence of nitrogen atoms within the crystal structure of the diamond. The more intense the yellow color, the rarer and more valuable the diamond. Fancy yellow diamonds can range in color from light yellow to intense yellow, and can even have undertones of green or brown. The most valuable fancy yellow diamonds are those with a pure yellow color, without any undertones. In addition to their color, fancy yellow diamonds are also valued for their brilliance, fire, and overall quality. They are often cut in a way that maximizes their natural color and sparkle, and can be found in a variety of different shapes, including round, pear, and cushion. Because of their rarity and beauty, fancy yellow diamonds can be quite expensive. However, they are also highly sought after by collectors and enthusiasts, and can be a worthwhile investment for those who appreciate their unique qualities.

Orange

Fancy orange diamonds are prized for their unique and rare color. They are among the rarest colored diamonds in the world, and their value is determined by several factors, including the intensity and evenness of the orange color, as well as the clarity, cut, and carat weight of the diamond. Fancy orange diamonds can range in color from light orange to deep orange, and may also have secondary hues of pink, brown, or yellow. The more intense and evenly distributed the orange color, the higher the value of the diamond. Fancy orange diamonds with a pure orange color and minimal secondary hues are the most valuable. Orange diamonds are also prized for their symbolism. Orange is often associated with energy, creativity, and warmth, and diamonds in this color are thought to represent these qualities. They are also believed to have healing properties and are often used in meditation and energy healing practices. Fancy orange diamonds are among the rarest of colored diamonds, accounting for less than 0.1% of all diamonds mined. Overall, fancy orange diamonds are highly sought after by collectors, investors, and jewelry lovers alike for their unique beauty and rarity.

Champagne

Fancy orange diamonds are valued for their warm color. They are among the rarest colored diamonds in the world and their value is determined by several factors, including intensity. Champagne diamonds are known for their soft and subtle shades of brown, yellow and orange. The value of a beautiful champagne diamond is determined by a number of factors, including the intensity and evenness of the color, clarity, cut and carat weight. They are a popular choice for use in a variety of jewelry, including engagement rings, earrings, pendants and bracelets. The warm tones of a champagne diamond can complement a range of skin tones and styles, and they can be set in platinum, white gold, yellow gold or rose gold. Although they are not as rare as some other colored diamonds, such as pink or blue diamonds, they are still relatively rare and carry a higher price. Champagne diamonds are mainly mined in Australia, Africa and South America, with the Argyle Mine in Western Australia being the largest producer of Champagne diamonds in the world. They offer a warm and understated alternative to traditional white diamonds and are a popular choice for those looking for a more unique and individualized piece of jewelry.

Brown

Fancy brown diamonds, also known as "chocolate" or "cognac" diamonds, are prized for their rich and warm earth tones. The value of a beautiful brown diamond is determined by a number of factors, including the automatic and uniformity of the brown color, clarity, cut and carat weight. The more intense and more evenly distributed the brown color, the more valuable the diamond. One of the reasons beautiful brown diamonds are valued is their versatility. They can be set in a range of metals, including white gold, yellow gold and rose gold, and their warm tones can combine a range of skin tones and styles. Another reason that beautiful brown diamonds are valued is their affordability compared to other smaller diamonds, such as pink or blue diamonds. While still relatively small, brown miniatures are smaller than other smaller diamonds, and their prices are generally lower. Fancy brown diamonds are mainly mined in Australia, Africa and South America. They are often found in the same mines as other patterns, and their color is thought to be caused by laters in the diamond's crystal lattice structure. They offer a beautiful and more accessible alternative to traditional white diamonds and their popularity has passed in recent years with more people looking for its unique and individualized jewelry.

Pink

Pink diamonds are not formed in two steps like regular 'white' diamonds, but in three. One of the world's most precious diamonds has a pink color. The gemstone, weighing no less than sixty carats, adorned the tiara of the wife of the Shah of Iran in 1959, during their royal wedding. The diamond is said to have come from a mine in India. How pink diamonds get their color is not yet fully understood. Regular, 'white' diamonds are formed deep in the earth's surface, where pure carbon, under immense pressure, arranges itself into the typical crystal structure of diamond. Then another geological process – a volcano, for example – is needed to bring the stones closer to the Earth's surface, where they can be mined. But with so-called colored diamonds, an extra step is required, which gives the stones color. Various hypotheses are circulating about this. New research from Australian geologists now appears to confirm one of these hypotheses. Based on analyzes of pink diamonds and (other) soil material from the Argyle diamond mine, located in the northwest of Australia, they conclude that the extra step in coloring the diamonds is in fact an intermediate step. Pink diamonds would certainly get their color when ordinary diamonds again had to deal with enormous compressive forces. It concerns forces of earth's plates that collide and rub against each other. Only then would the discolored diamonds begin their journey to the Earth's surface. At the Argyle mine, which has long been the main source of pink diamonds, geologists were also able to date two of the three steps in diamond formation. About 1.8 billion years ago, existing diamonds in the deep subsurface would have turned pink under the influence of tectonic forces. At that time, two tectonic plates collided with each other, forming a continent. When that broke up 1.3 billion years ago, it created space for the pink diamonds to migrate upwards.

Setting

Solitaire

The word "solitaire" refers to the fact that only one stone is placed in the setting. The solitaire setting is therefore the most sober setting of all. It gives a simple and classic look. If you want all the attention on your gemstone, this setting is the most appropriate. There are several types of solitaire settings, including the tiffany setting, which has a high setting that protects the stone and increases the brilliance of the stone, and the cathedral setting, which features metal arches that hold the stone. A solitaire setting can therefore be performed with prongs or claws, but the diamond or gemstone can also be bezel set in a pot or case or directly in the plate or metal. This is not performed by our master goldsmith but by our specialized solitaire setter. Yes, even the typesetting itself is also subdivided into all kinds of specializations. If you want your precious gemstone to be processed into a ring, pendant, earring or bracelet with the greatest craftsmanship, then you choose a workshop with more than thirty years of experience in the middle of the Antwerp diamond district.

Consecutive

A consecutive gemstone setting is a jewelry design in which gemstones are placed next to each other in a row or band. This setting is often used for bracelets, rings, necklaces and earrings and it's most popular for engagement rings and wedding rings. Sometimes the gems are placed so that their edges touch, creating a continuous pattern. This ensures a very sleek, elegant and polished appearance of the jewel. There are various techniques to make a contiguous gemstone setting, such as channel setting, pavé setting or bead setting. Pavé setting is the most common technique, in which small gemstones are placed closely together and secured with small claws or pins. Channel setting and bead setting are often used for larger gemstones and give a similar look, but with a slightly different construction. A contiguous gemstone setting can contain different types of gemstones, such as sapphires, rubies, emeralds, topazes, diamonds, and more. The design can range from simple and classic to intricate and detailed.

Pavé

A pavé is a style of jewelry or jewelry setting in which small diamonds or other gemstones are embedded into the metal base of a piece of jewelry, with the surface of the piece of jewelry covered with gemstones in an even pattern. The term "pavé" comes from the French word for paved, which refers to the way the gems are set closely together, giving the appearance of a paved street. A pavé setting is often used in engagement rings, wedding rings, earrings, pendants and bracelets. It gives a beautiful sparkle and a luxurious look to the piece of jewelry. A pavé setting is a delicate and labour-intensive technique in which the gemstones are carefully set to make the piece of jewelery look as beautiful as possible. It is important to know that the gemstones in a pavé setting are very small and therefore more fragile than larger gemstones. It is important to properly maintain the jewelry with pavé settings and to have it checked regularly by a jeweler to prevent gemstones from falling out.

Halo

An entourage or halo setting is a jewelers technique in which a central gemstone is surrounded by smaller stones. They light up the whole and accentuate the central stone. That is why they are sometimes called accent stones. This setting is usually used in rings, earrings and pendants, where the central stone is usually the largest and the smaller stones around it are set in the shape of the central gemstone. This can be circular, oval, square, rectangular or any fantasy shape. The gemstones can be of the same kind or can have different colors or origins depending on the taste of the customer and the availability of the gemstones. An entourage setting is often chosen for engagement rings and wedding rings, because it gives an extra dimension to the center diamond or gemstone. It creates a beautiful sparkle and an impressive look to the ring or pendant, making it look even more impressive.

With Side Stones

The setting with side stones is a popular style for gemstone jewelry, known as a "solitaire with accents". It typically features a larger center gemstone, which is the focal point of the jewel, and smaller gemstones on one or either side of the center stone, often set into the band itself. The center gemstone can be a diamond or any other type of gemstone, depending on personal preference and budget. The smaller accent stones are often diamonds or other precious stones, and can add sparkle and visual interest to the overall design. This type of setting can be a beautiful choice for an engagement ring or other special occasion, as it creates a classic, elegant look that is both timeless and versatile.

Three-Stone

The three-stone setting or trilogy setting usually has a larger central gemstone and two smaller gemstones on either side of it. The smaller stones can be the same type of gem as the central stone or a different type of gem. The three stones are usually diamonds, but can also be other precious stones such as sapphires, emeralds or rubies. The design is meant to represent the past, present and future, making it a popular choice for engagement rings or anniversary gifts. The trilogy design can be made into rings, bracelets, necklaces and earrings.

Two-Stone

The "two stone setting" or "toi et moi setting" is a specific type of jewelry setting where two stones are placed next to each other, often with a little bit of space between them. The name "toi et moi" is French for "you and me", which refers to the symbolism of the two stones placed together. This type of setting became popular in the late 19th and early 20th centuries and was often used for love rings and other jewelry. The two stones in the setting can be different shapes and sizes, although they are roughly the same size. A variant of the toi and moi setting is the "infinity setting", where the stones are placed on the equivalence of a loop resembling the infinity symbol. This can also be seen as a symbolic way of expressing the closeness of two people. The two-stone setting can be used with different types of gemstones, but diamonds are the most likely because of their hardness and durability.

Setting Details

The type of setting can have a significant influence on a jewel in terms of its appearance, durability, and overall value. A setting is the precious metal frame that holds a gemstone in place, and different types of settings can highlight or detract from the beauty of a gemstone. For example, a prong setting allows more light to pass through a gemstone, which can enhance its brilliance and sparkle. On the other hand, a bezel setting encases a gemstone in metal, providing more protection but potentially obscuring some of its facets. The type of setting can also affect the durability of a jewel. A secure setting can help to prevent gemstones from becoming loose or falling out, while an insecure setting can increase the risk of damage or loss. Finally, the type of setting can impact the overall value of a jewel. A well-crafted, high-quality setting can enhance the beauty and durability of a gemstone, which can increase its value. Conversely, a poorly made or inappropriate setting can detract from a gemstone's natural beauty and decrease its value.
