Rio Tinto’s recent tender of rare blue diamonds from the Argyle Diamond Mine in Western Australia set “record prices” and “exceeded expectations,” a statement said – although the company declined to be more specific about its results.
Known as the “Once in a Blue Moon” collection, this first ever collection comprised a range of precious blue and violet diamonds, 16 lots weighing in total 287 carats. The collection was showcased in Tokyo, Hong Kong and Perth, with bids closing on April 8.
“We have been overwhelmed by the enthusiasm from new and existing colored diamond collectors around the globe, especially in such a challenging economic environment,” said Josephine Archer, sales and marketing manager for Argyle Pink Diamonds. “With only ten year’s production left at the Argyle mine there is clearly a growing awareness that the opportunities to purchase these collections are rapidly diminishing.”
