Rio Tinto has launched the Beyond Rare Tender, an inaugural collection of 48 lots of polished fancy-colored diamonds.
The miner will offer 87 diamonds in total, including its legacy inventory of pink and red stones from the shuttered Argyle diamond mine in Australia and yellow diamonds from its Diavik site in Canada, it said on Tuesday.
The new collection is “a testimony to the ongoing demand for highly collectible natural diamonds,” said Sinead Kaufman, chief executive of Rio Tinto Minerals. “This carefully curated collection of rare jewels will be in strong demand by the world’s finest jewelers, collectors and diamond connoisseurs.”
Titled The Art Series, the invitation-only tender is inspired by the art world, the company said. The combined weight of the diamonds is 29.96 carats.
They include the following:
• Seven diamonds consisting of Argyle pink stones and yellow Diavik ones, which the company says will be accompanied by bespoke artwork.
• An offering of 11 matched pairs of colored diamonds.
• Thirty single diamonds, including one distinctive fancy-red Argyle diamond.
The closure of the Argyle mine in Australia and the continued strong demand for exceptional fancy pink and red diamonds means the market for Argyle pink and red diamonds “have never been stronger,” said Patrick Coppens, general manager of sales and marketing for Rio Tinto’s diamonds business.
The 48 lots will be shown in Australia, Switzerland and Belgium, with bids closing on November 20.
