Cognac Diamonds & the Argyle Diamond Mine
The Argyle Diamond Mine is the richest diamond deposit in the world. It is situated near Lake Argyle, a man-made dam at Smoke Creek in the remote north of Western Australia. The Argyle Diamond Mine produces more than a third of the world's total annual supply of pink, brown, and white diamonds. And over 50% of the worlds brown (cognac) diamonds, the remainder are found in Africa.

The Cost of Cognac Diamonds
Brown diamonds are usually less expensive than any other colors due to the fact that they are less appealing to the majority of consumers. For many years people have been used to the brilliance of clear, white diamonds and the price depends more on popularity and fashion rather than on rareness. Cognac colored diamonds sell at 30% less than comparable white diamonds. The color descriptions of brown diamonds are now described and marketed as Champagne or Cognac colored to increase their overall appeal. And tastes in diamonds are changing - the existing and much lower selling price of cognac colored diamonds make a very good selling point.

A Diamond can occur in nearly any color, though yellow and brown are by far the most common. The Cognac diamond is a member of the Carbon family and is the hardest substance known. The word Diamond is derived from the Greek word "adamas" which means "hardest metal" reflecting the property of the stone.

Definition of Diamond Color

The most common impurity, nitrogen, causes a slight to intense yellow coloration depending upon the type and concentration of nitrogen present. Brown or Cognac “amber” diamond crystals show some deformation called “brown graining”. They also contain nitrogen.
