Argyle Diamond Mine

The Argyle mine in Western Australia is one of the world's largest diamond producers by volume, producing more than 750 million carats of rough diamonds since operations began in the 1980s. Most of the diamonds mined there are of relatively low quality. However, it is the primary source of the rare and valuable pink diamond, producing more than 90% of the world's supply, and is also a major source of champagne, cognac, and blue diamonds. What percentage of Argyle's diamonds are gem quality? More...

Only 5% is considered gem-quality, with the rest being either near-gem quality or industrial grade.

...that 5 % "is somewhat below world averages of about 20% of mined diamonds qualifying as gem-grade. "

A quite fascinating article. Thank you for sharing; however, one question came to my mind while reading. I was wondering if anyone here knows how they secure the area from would be diamond thieves and other undesirable characters? They must surely have to have some of the tightest security measures of anyone in the world. I would think that would be the case, but if someone might share some additional information there, I would be most appreciative.

The really cool bit is thinking about how they got there!

Quote:
The Kimberley diamond region consists of a central core of a thick series of nearly flat-lying sedimentary and volcanic rocks that were deposited between 1.6 and 1.9 billion years ago. These rocks form the Kimberley Plateau. They are underlain by a basement of crystalline igneous and metamorphic rocks, which are not exposed on the surface of the plateau. Recent investigations have indicated that the basement is of Archaean age, that is, more than 2.5 billion years old.

ancient basement


a bit of sediment on top





a bit of volcanism





first you open pit


then you tunnel





Well, I think it is cool, anyway Applause Whistle

ARGYLE DIAMONDS

BEYOND RARE


Of the 20 million carats of rough diamonds that are produced annually, less than 0.1% are pink. Argyle pink diamonds are rare; in fact they are beyond rare. With just an estimated decade of supply remaining in the mine, as time passes the Argyle pink diamond becomes evermore precious.

To own a pink diamond is to be
the custodian of an unsurpassed heirloom;
to gaze upon it is to view unfathomable beauty;
to give one is to impart a gift that is truly beyond rare.
