Argyle coloured diamonds sparkle for Rio Tinto


Miner announces winning bids for red, pink and blue stones.

Rio Tinto is celebrating the success of its recent coloured diamonds tender, with the stones described as “keenly contested” with prices indicating a strong appreciation for fancy coloured stones.

The stones, sourced from Rio Tinto’s Argyle mine in Australia, were part of its 2012 tender collection of almost 80 stones, including 56 single pink diamonds, two red diamonds and 19 blue diamonds.

The stones are said to have attracted bidders from around the world, from both emerging and established markets.

Josephine Johnson, manager for Argyle Pink Diamonds, said: “We were delighted to see such a strong appetite for this unique rainbow collection [of stones].

“Several beautiful diamonds from the collection have a new home in India, an important emerging market for rare pink diamonds, and the hero blue diamond, Argyle Elektra, is destined for Japan, the most established market for pink diamonds.”

One of Argyle Pink Diamonds largest partners in the Asia Pacific region, John Glajz, bid on the most valuable pink diamond in the collection – a 1.32ct square radiant cut stone with a fancy purplish pink colour, dubbed the Argyle Siren.

He said: “I was thrilled to receive the news. This is a rare diamond from a rare collection, incomparable from the perspective of a connoisseur and I look forward to designing an heirloom piece of jewellery to honour its heritage.”

The tender took place at Kensington Palace in London on October 9, where Rio Tinto also showcased an exhibition of pink diamond jewellery worth more than $65 million (£40.5m), held to celebrate royal connections in the Queen’s Diamond Jubilee year.

Jean-Marc Lieberherr, chief commercial officer for Rio Tinto Diamonds, said: “These rare Argyle diamonds provide the escalating intrinsic value of an investment and are destined for the exclusive echelons of the world’s most sophisticated collectors.”

Rio Tinto’s Argyle Diamond Mine produces more than 90% of the world’s pink diamonds.
