Six years after closing Western Australia’s iconic Argyle mine, Rio Tinto has sold its remaining inventory of rare pink diamonds and handed over ownership of the Argyle Pink Diamonds brand to British jeweler Boodles. The Argyle mine officially ceased operations on November 3, 2020, ending a 37-year run during which it supplied over 90% of the world's pink diamonds. Boodles plans to feature this final, historic reserve as the cornerstone of an exclusive high-jewelry collection launching in 2027.
