Rio Tinto releases pink diamond and gold ingot

Rio Tinto (LON: RIO) announced Monday the release of a limited edition pink diamond ingot in honour of its Australian Argyle underground mine opening.

Crafted by the Perth Mint, 168 individually numbered ingots will be sold worldwide, at a price of about C$4,200 (AU$4,440, with tax $4,880).

The ingot is set with seven rare pink diamonds embedded in a one ounce bar of 22-carat pink gold, with an emblem of the boab tree on the reverse side.

The Argyle mine in Western Australia produces more than 90% of the world's pink diamonds.

Buyers can order the ingot via the Perth Mint.
