The color of brown diamonds

No other diamond color has such a variety of names as brown diamonds. The color of brown diamonds is compared to spices and luxury foods, so that names like Chocolate diamond, cocoa diamond, champagne diamond, cognac diamond, cinnamon diamond, tobacco diamond, caramel diamond, espresso diamond, mocha diamond or amber / amber diamond are common.

The different names were chosen for a reason. Brown diamonds dreamed of being an inconspicuous gemstone for many years. The idea of ​​giving brown diamonds a nice-sounding name dates back to the 1980s / 90s. Brown diamonds should no longer the "boring" diamond status have to be used for industrial purposes or for dyeing. Brown diamonds should not only be set in men's jewelry, but also adorn women. With the Imaginative names were popular with the diamond dealers.

Only the name Chocolate Diamond or Chocolate Diamond is reserved for brown diamonds that come from Le Vian **. The jeweler had the name Chocolate Diamant ** and Nude Diamant ** registered as a trade name in 2000.

The richness of the nuances of brown diamonds results from the interplay of three criteria that essentially determine the color of fancy diamonds.

  • Primary color: the color that the viewer perceives first
  • overtone: the color that is recognizable as a subtle hint of color diamonds
  • saturation: the color strength, which ranges from pale, pastel to strong

The The primary color of brown diamonds is brownwhich can be both pure brown with no overtones or with a hint of another color.
Whether the overtone is considered harmonious and aesthetic is determined with the help of the color wheel. Overtones whose color on the color wheel is close to the primary color support the primary color positively. The diamond appears to be of higher quality. Colors that are too far away make the primary color appear impure.

Based on the color wheel, brown diamonds with a tinge of red or pink are of high color quality, as the overtones mentioned above highlight the warm character of brown diamonds. Yellow, orange, or green overtones are further away from brown on the color wheel and are considered less desirable.

The exact color description determines how clearly the overtone emerges. A fancy orange / green / yellow brown diamond is a brown diamond with a pronounced orange / green / yellow tinge. A fancy orangy / greenish / yellowish brown diamond only suggests a hint of orange, green or yellow. It is not uncommon for several overtones to be combined in one stone, e.g. Fancy greenish yellow brown diamond.

The fact that the term fancy is always put in front of the color description of colored diamonds can be explained with the distinction to white diamonds and at the same time belonging to the fancy diamonds. At the same time, the description fancy indicates the degree of color saturation, which increases from fancy light to fancy, fancy intense, fancy vivid, fancy deep to fancy dark.


Champagne diamonds and cognac diamonds

All of this information was once specified by the Gemological Institution of America (GIA) ** in order to categorize colored diamonds according to uniform standards.
The names champagne, cocoa or cognac diamonds are not precisely defined according to the GIA.
Still, the term has become Champagne diamond for light brown diamonds with a tinge of yellow or gold naturalized while Cognac diamonds darker brown diamonds with an orange or red tinge are.

Independent of the GIA color scale, the Australian Argyle Mine ** has created a scale especially for brown diamonds, according to which the brown Argylle diamonds are classified from C1 to C7. C1 diamonds are light champagne diamonds whose color becomes stronger and darker, so that at the end of the scale with C7 there are dark cognac-colored diamonds.


The cause of the color of brown diamonds

Chemically speaking, diamonds - white and colored - are made of pure carbon (C).

Whether a diamond is white or colored is determined by additional elements embedded in the crystal lattice, growth disorders, crystal lattice defects or the influence of radioactive radiation.

In the case of brown diamonds, they are Growth lines - so-called graines or grain lines, which explain the color of brown diamonds are. Under high-resolution microscopes, these lines appear as extremely fine lamellae in brown color.


Natural occurrence of brown diamonds

The most of the brown diamonds come from the Argyle mine in Australia. Around 80 percent of the diamonds mined there are brown diamonds. Brown diamonds are also found in South Africa, the Congo and Brazil.

Brown diamonds - brown minerals

Because of their color, brown diamonds can be confused with other brown gemstones and minerals, including, for example, smoky quartz, topaz, zircon, scapolite, andalusite and amber. Colored quartz (e.g. cognac quartz), imitations of rhinestones or glass as well as zirconia grown in the laboratory, which is used as an imitation for any mineral, look similar to brown diamonds.

The authenticity of brown diamonds can be easily determined by determining the composition, Mohs hardness, luster, density, cleavage and breakage as well as transparency.


The value of brown diamonds

Brown diamonds are those of all color diamonds whose price is on average below other colors.
However, depending on the quality of the stone, brown diamonds can fetch prices that vary between Move 2,000 and 20,000 euros per carat.

The price of diamonds is not calculated solely on the basis of color. The value of a diamond results from the factors color, purity, weight and cut - the so-called 4C (Color, Carat, Clarity and Cut).

Brown diamonds with a high color saturation, i.e. dark, strong colors, are rated higher than diamonds with a weak color. If the color is pure brown, the value is also higher than for orange, yellow or green-tinged brown diamonds. A red or pink cast, on the other hand, is considered positive.

It is similar with purity. Brown diamonds of flawless transparency, in which even under 10x magnification with the magnifying glass no inclusions of other minerals, gases or liquids can be seen, are more valuable than eye-clean copies.

Weight is another very important factor. Large brown diamonds cost a higher carat price than small diamonds of the same color and clarity.

The cut as such should not be neglected either. Incorrectly worked facets, overlapping facets or missing / additional facets affect the overall appearance of the cut diamond and the brilliance (for more details see: The evaluation of the quality of colored gemstones).
