A selection of the finest rough diamonds from Rio Tinto’s Canadian and Australian mines will be tendered to diamond specialists from around the world in October and November. Headlining Rio Tinto’s forthcoming “Specials” Tender, which showcases rough diamonds greater than 10.8 carats, is Lot number 1, Diavik Helios, a 74.48 carat Fancy yellow diamond. The Diavik Helios takes its name from the pure yellow sunlight emitted by the mythical Greek God of the Sun.

Fancy yellow diamonds are rare finds from the Diavik diamond mine in the remote Northwest Territories of Canada which primarily produces high quality white diamonds. Patrick Coppens, General Manager, Sales and marketing for Rio Tinto’s diamonds business said “Since the Diavik mine began production in 2003 it has produced on average only five large yellow diamonds each year, in effect less than 0.001 per cent of Diavik’s annual production.

The Specials tender is also notable for including the last of the rough diamonds in this category from the Argyle mine in the east Kimberley region of Australia. 28,399 carats of rough Argyle diamonds are included, showcasing the famed Argyle coloured diamonds, together with a beautiful 26 carat white gem quality rough Argyle diamond.

The Tender will be physically showcased in both Antwerp and Tel Aviv, together with virtual and online viewings to cater for COVID-19 restrictions. Bids close on November 9, 2020.
