Rio Tinto’s Rare Red Diamonds

Each year, Rio Tinto, the second largest diamond mining company in the world, hosts the Argyle Pink Diamonds Tender. This year, the collection consists of 55 diamonds – 51 pink and purplish red diamonds, and four Fancy Red diamonds.

Fancy Red diamonds are extremely rare. So rare, that only 13 have been featured in the annual tender in the last 30 years. These diamonds come from Rio Tinto’s Argyle mine in Australia, and the pieces featured in the yearly event are some of the rarest and most valuable diamonds in the world.

The diamonds will be displayed in New York, Sydney, Perth and Hong Kong, while investors submit their bids. The bidding deadline is October 8.
