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, champagne, and white 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. The color descriptions of these diamonds are now described and marketed
as Cognac or Champagne to increase their overall appeal.
Champagne Diamonds
What exactly are Champagne Diamonds? Champagne diamonds have a tint of
brownish
body color and the term champagne is an alternative way of describing
brown diamonds. Diamonds can occur in nearly any color,
though yellow and brown are by far the most common. The Champagne 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
What is the Definition
of a Champagne Diamond? Colored
diamonds contain impurities or structural defects that cause the
coloration. The most common impurity, nitrogen, causes a slight to intense
yellow coloration depending upon the type and concentration of nitrogen
present.
Brown or Champagne “amber” diamond crystals show some deformation called “brown
graining”. They also contain nitrogen.
