Bidding for the carefully curated collection was strong, with individual, multiple and global bids and a broad geographic spread of successful bidders from Australia, Europe, Japan, Hong Kong, Singapore, US and Israel.

Sinead Kaufman, Chief Executive of Rio Tinto Minerals said “We are delighted with the results from this new sale format for Rio Tinto’s diamonds business, delivering results that reflect the global demand for highly collectible natural coloured diamonds and the resulting value creation.”

Careful custodianship is a hallmark of Rio Tinto’s diamonds business and The Art Series collection, including seven sets of diamonds (Masterpieces), 11 perfectly matched pairs  and 30 single diamonds, was in strong demand from luxury jewellers around the world.

The only Fancy Red diamond in the collection was won by Kununurra-based bespoke jeweller, Kimberley Fine Diamonds. Owner Frauke Bolten-Boshammer, one of the first retailers to sell Argyle pink diamonds, said “I am delighted that this exceptional gem will stay in Australia, entrusted with Kimberley Fine Diamonds to continue its onward journey as one of the few highly coveted Fancy Red diamonds produced from the Argyle Diamond Mine. It is an extraordinary diamond of esteemed provenance, with a beauty that reflects its magnificent birthplace here in the East Kimberley region of Western Australia.”

There was also intense interest from the Japanese market where Argyle pink diamonds have long been revered by Japanese jewellery designers. Distinguished jeweller, Gimel, representing the ultimate in bespoke Japanese craftsmanship, was a successful bidder in The Art Series. Gimel has been creating beautiful hand-crafted Argyle pink diamonds pieces for the past 25 years, crafted from an atelier carved into a mountainside near Japan’s Setouchi National Park. Kaoru Kay Akihara, Gimel’s lead designer, said “We have a long relationship with the beautiful and rare Argyle pink diamonds and we are looking forward to transforming our successful bids into works of art, to be treasured for future generations.”

Harsh Maheshwari, Executive Director, said “We see strong ongoing market demand for the truly rare – irreplaceable fancy-coloured natural diamonds with impeccable provenance. These diamonds are in a league of their own and will consistently transcend the fluctuations of economic cycles.”

Almost the entire world’s supply of rare pink, red, blue and violet diamonds come from Rio Tinto’s Argyle Diamond Mine which ceased production on 3 November, 2020.
