A million-dollar Argyle red diamond gold coin has sold within 48 hours of its unveiling. Rio Tinto Diamonds says it was bought by Tiara Gems and Jewellery, a Dubai-based company specializing in rare and important fancy-colour diamonds, unique collectibles, and heirloom jewellery.
A rare 2.83-carat violet diamond unearthed from Rio Tinto’s Argyle mine will be the centrepiece of its 2016 Argyle Pink Diamonds Tender. Named ‘Argyle Violet,’ the diamond was discovered in 2015 and cut from a 9.17-carat rough stone. It is the largest violet diamond recovered from that mine.
