Limited edition ingot celebrates Australia's world famous pink diamond mine

A limited-edition pink gold ingot, set with beautiful and rare pink diamonds, has been designed to commemorate Rio Tinto's Underground Mine in Australia.


The leading international mining group Rio Tinto is delighted to unveil a limited-edition pink diamond ingot, created to commemorate the Argyle Underground Mine in Western Australia.

The Argyle Diamond Mine now uses the latest in block caving technology to extract more than 90 per cent of the world's pink diamonds, which are sold in a broad range of colours around the globe. 

A selection of the extremely rare pink gems has been carefully hand-set into one of 168 individually numbered pink gold ingots. Each depicts a Boab tree embedded with six Argyle pink diamonds - a reminder that these rare pink gems were formed beneath the earth's surface more than a billion years ago, under the ancient Boab trees in the East Kimberley region of Australia.

Because of their extreme rarity, pink diamonds often command a far higher price than their white counterparts. Each ingot is valued at US$4,880 and will be released for sale worldwide.
