Hong Kong-based Kunming Diamonds recently joined a group of 13 exclusive authorised partners entrusted with the "care and custody' of Argyle pink diamonds, Australian miner Rio Tinto announced.

In 2019, Kunming Diamonds acquired the entire Argyle Pink Everlastings™ Collection, a one-off exclusive selection of certified Argyle pink and red diamonds. Established in 1987, the company is a leading fancy colour diamond expert in Asia.

Harsh Maheshwari, director of Kunming Diamonds, commented, “No other diamonds on earth match the rarity and provenance of Argyle pink diamonds. This is a wonderful honour and showcases our commitment to bringing the world’s rarest diamonds to our global partners and client base.”

Rio Tinto's celebrated Argyle mine faces an impending closure by the end of 2020. The mine has produced more than 825 million carats of rough diamonds since it began production in 1983.
