About Fancy Brown Diamonds the most commonly mined

Fancy brown diamonds are the most commonly mined fancy color in the world, but until very recently were overlooked for being perceived as dull and uninteresting. Fancy brown diamonds burst onto the diamond market in the 1980s, when the Argyle Mine in Australia, first famous for their noteworthy pink diamonds, launched a massive marketing campaign to promote these diamonds.

By coining the titles Champagne Diamonds for the lighter colored brown diamonds and Cognac Diamonds for the darker shades of brown, they were successful calling the world’s attention to these beautiful stones. Brown diamonds are also commonly referred to as Chocolate diamonds. Associating the brown diamond with the warm luxury of these products worked wonders, and fancy brown diamonds of all shades have now earned their niche in the world of fancy colors. They are now synonymous with uniqueness and luxury, and highly prized by collectors and consumers alike. Brown stones have become prevalent as accents or centers tones in jewelry.


Brown diamonds are mined in South African, Siberia, and most commonly in the Argyle Mine in Australia.

Cause of Color

Fancy Brown Diamonds are the equivalents of yellow diamonds when it comes to the cause of their coloring. When a white diamond displays a dark enough yellow or brown color, it falls off the D-Z colorless scale and enters the class of colored diamonds.

Their brown coloring comes from nitrogen impurities in the atomic structure of the diamonds. Although brown diamonds can sometimes be graded the same way as the other fancy colors, with shades ranging from Fancy Light Brown to Fancy Deep Brown. However they are more commonly graded by the unique Champagne Diamond scale, created by the Argyle Mine. On this scale, brown diamonds are graded in increasing color depth, from Light Champagne (C1-C2), to Medium Champagne (C3-C4), to Dark Champagne (C5-C6), and finally Fancy Cognac (C7).

Although pure brown diamonds are hard to come by, they are more easily found with secondary hues such as pinkish brown, yellowish brown, and orangey brown. These diamonds can be enchanting in a variety of colors, and should be a definite consideration for anyone on the search for a beautiful colored diamond. They carry the extra advantage of being extremely affordable!

The Incomparable Diamond was the fourth largest uncut diamond, weighing 890 carats when it was discovered in Zaire (today the Democratic Republic of Congo).

Investing in Champagne Diamonds

The market for fancy brown diamonds is one of the fastest growing luxury markets in the world. The past five years have seen incredible growth in this industry, with a jump from zero to 5 billion dollars, and new price records are being set daily for brown diamonds.

Since then, however, their beauty and value has become widely recognized and their prices have been rising steadily.

Most brown diamonds in the world are mined in the Argyle Mine, slated to close in 2018. As they follow the same course that pink diamonds followed on their rise to fame, champagne, cognac or chocolate diamonds are bound to only keep growing in popularity.
