Rio Tinto Unveils First Argyle Brand Jewellery

Australian miner Rio Tinto has debuted its first Argyle Pink Diamonds jewellery piece since the closure of the Argyle deposit in Western Australia in November 2020.


The AU$6 million ($3.8 million) Argyle Romantica ring that contains 3.42 carats of pink, red and blue diamonds from the mine is the first piece produced under the Argyle Pink Diamond Icon Partner programme. The programme is part of a strategy to protect the provenance of Argyle Pink Diamonds.


The ring is significant because it demonstrates the union of five exceptional Argyle Pink Diamonds, totalling 2.31 carats in weight, including a 0.75-carat fancy red diamond, two fancy vivid purplish-pink diamonds and two fancy deep pink diamonds. The five red and pink diamonds are showcased in an intricate setting that includes 1.11 carats of smaller blue and pink Argyle diamonds.


The ring was created by Singapore-based designer John Glajz, one of Rio Tinto’s two partners in the brand. The miner is collaborating with both designers to create one-of-a-kind jewellery pieces, and limited-edition collections using the remaining supply of polished Argyle Pink Diamonds.


Rio Tinto also noted that it will introduce a concierge trading platform for certified Argyle pink diamonds and a new tender channel, Beyond Rare, for special sales events.
