Bids for this year's Tender collection of 56 single pink diamonds, including two red diamonds and an additional 19 lots of blue diamonds from Rio Tinto's Argyle Diamond Mine in Western Australia, closed on October 15th. %% Successful bidders for the 2012 Tender collection were from both established and emerging markets. Josephine Johnson, Manager for Argyle Pink Diamonds said, "We were delighted to see such a strong appetite for this unique “rainbow collection”. 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 ElektraTM, is destined for Japan, the most established market for pink diamonds. Across all other markets, including their Australian birthplace, there was strong evidence of the Argyle pink diamond's compelling combination of rich provenance, exceptional craftsmanship, and natural beauty.” %% John Glajz, Argyle Pink Diamonds’ largest Asia Pacific partner was the successful bidder of the most high valued diamond from the collection, Argyle SirenTM, a 1.32 carat square radiant cut Fancy Vivid Purplish Pink diamond. %% Commenting on his newest attainment, John exclaimed, “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.” %% Many of the successful bidders were part of the exhibition at Kensington Palace on October 9th, where more than US$65 million of rare pink diamond jewellery was showcased to celebrate royal connections in the Queen’s Diamond Jubilee year. Speaking on the occasion, 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.” %%
