Rio Tinto achieved record value at its 2020 Argyle Pink diamonds Tender, after bidders raised prices for the rare diamonds as supply has come to an end. The company offered 62 pink, red, blue and violet diamonds, weighing a total of 57.23 carats. It allowed participants to view the diamonds using live streaming and a virtual portal at locations in Antwerp, Singapore and Perth, Australia, due to travel restrictions associated with the coronavirus pandemic.
