Argyle Diamond Mine - Australia
Natural diamond sources have been discovered in approximately 35 different countries around the World across several continents. Diamonds, and consequently mines like the Argyle Diamond Mine, are found in areas where there have been volcanic activity or erosion and where natural elements such as streams, rivers and even glaciers might have taken them. When such sources are discovered mines, such as the Argyle Diamond Mine, often follow. The Argyle Diamond Mine is the world’s largest diamond mining operation by volume, although not by value due to the quantities of less popular brown diamonds that it produces.

Diamond Mines

Argyle Diamond Mine - Pink Diamonds
Pink diamonds are extremely rare and the Argyle Diamond Mine is the only known significant source of pink diamonds, producing 90 to 95% of the world's supply.  Crystal lattice defects during the formation of diamonds cause the pink color.

Argyle Diamond Mine - Brown Diamonds
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 “amber” diamond crystals show some deformation called “brown graining”. They also contain nitrogen. The Argyle Diamond Mine produces 80% brown diamonds. Brown diamonds are usually less expensive than any other colors due to the fact that they are less appealing to most customers. The color descriptions of these diamonds are now described and marketed by the Argyle Diamond Mine as Cognac or Champagne.

Information about Diamond Deposits
Diamonds reach the surface of the earth via volcanic pipes or via placer / alluvial deposits. The purpose of the mines is the extraction of valuable diamonds from the earth. The mines are plant operations built to extract diamond crystal from either underground or from the surface. When diamonds are extracted underground, the mine needs a system of excavations in the rock to gain access to the kimberlite rock. There are a limited number of commercially viable diamond mines currently operating in the world which use tunnelling and excavation methods. However, diamonds are also mined using the Placer or Alluvial mining methods when host rock is washed away by streams and rivers and diamonds are deposited as sediment in the stream sands in 'placer deposits' which also called Alluvial deposits.
