The latest tender of 62 rare pink, red, blue and violet diamonds from major Rio Tinto’s Argyle mine, in Western Australia has delivered a record result, reflecting their extraordinary rarity and unique provenance.

The 2020 collection continued its trajectory of double digit price growth and a record number of participants with successful bidders from eight countries.

The miner said this week that while bids and values remain confidential, Lot Number 1, the 2.24 ct Argyle Eternity™, the most valuable diamond in the collection and the most valuable fancy vivid diamond in the tender’s 37 year history, was sold to Hong Kong fancy coloured diamond specialist, Kunming Diamonds.
