Getting a Diamond Ring
the Hard Way

The Argyle Diamonds claims to be the largest diamond supplier in the world, accounting for one-quarter of the world's production.  This mine in the remotest area of Western Australia is the largest open pit diamond mine in the world and in addition to top-quality gems, near gems, and industrial diamonds, produces almost the entire supply of natural pink diamonds. 
You have to move a lot of earth of get to the good stuff ...  And most of that earth-moving equipment is driven by women.  Better safety records.  Take THAT, gentlemen.
The company says 11 million tonnes of ore goes into the processing equipment each year....and 30 million carats of diamonds come out.

A small museum at the mine contains geologic displays, explanation of the diamond production process and examples of the mine's output, such as a bag of "run of the mine" diamonds of about 1 carat (above left) and the diamond found at Argyle, a 42.6 carat diamond (above right).  They keep the giant in the museum at the mine for sentimental reasons ... and besides, it's not worth anything.  It's only of industrial quality. 

Of course, no tour is complete without a trip to the gift shop.  The diamond mine tour was no different.   The "souvenirs" were just more expensive.

The pilot who flew us to the mine gave a lesson in selecting diamonds.  Then the ladies of the gift shop produced rings with Argyle mine diamonds.
