Brown, champagne and cognac colored diamonds
Brown is the most common color in colored diamonds. A look back at history shows that light and luminous stones were preferred. For this reason, brown diamonds were initially excluded from the glamorous world of rare colored diamonds. Only a few connoisseurs appreciated the brown diamonds and had them incorporated into men's rings. Today they have become an integral part of the world of jewelry. Brown colored diamonds also represent a beautiful and cheaper alternative to other colored diamonds.

Formation of brown diamonds
The deeper the brown of a color diamond, the rarer and more valuable it is. There are different causes for the brown coloring of diamonds. So-called “grainings” are often the reason for the brown color. These are irregularities that occur as a diamond grows. They are only a few hundredths of a millimeter long and cannot be seen with the naked eye. The grainings can have a brownish color in the form of faint lines, which in turn make the almost colorless diamond appear a very faint brown. Brown coloring can also occasionally be traced back to the color center. Isolated nitrogen atoms are embedded in the crystal lattice.
Overtones in brown diamonds
Brown diamonds with a red overtone are highly sought after and therefore such an overtone has a positive effect on the value of a brown diamond - meaning that such a diamond is more expensive. Overtones other than red have a price-reducing effect on diamonds with the primary color brown. For all those who are looking for a real bargain and value the individual color rather than the rarity, such diamonds are a real alternative.
Brown diamond locations
Brown diamonds are found in various regions of the world. Particularly intense, chocolate brown diamonds come primarily from the Argyle mine in Australia. In the 1980s, the yield of brown diamonds from this mine was very high, so Australian traders launched a campaign to market the previously unpopular diamonds. For example, they introduced the terms “champagne” for lighter diamonds or “cognac” for darker diamonds. The marketing campaign was crowned with success and today the brown colored diamonds adorn a wide variety of jewelry.
