Tiffany & Co. Acquires Bespoke Curation of Rare Argyle Pink Diamonds Sourced from Rio Tinto’s Renowned Australian Argyle Diamond Mine

Jan 25, 2023

NEW YORK, NY—Today, Tiffany & Co. announces that it has acquired a final bespoke curation of rare pink diamonds from the now-closed Argyle Diamond Mine in Australia. Located in the country’s East Kimberley region, a remote area of Western Australia, the renowned mine was open from 1983 until November 2020. It was and remains virtually the only source for pink diamonds in the world. While mining has ceased, Argyle held a small cache of diamonds that were unearthed in the final mining period. In early 2022, Argyle approached Tiffany & Co., exclusively offering the House this unique collection of their remarkable diamonds. This is the first time that Argyle has curated a bespoke collection named in honor of a jeweler; the fact that Tiffany & Co. was chosen reflects the House’s position as the premier purveyor of the world’s most coveted creations and exceptional diamonds.

“This extraordinary collection of 35 Argyle Pink™ Diamonds showcases the range of colors that Argyle diamonds are famous for, including Fancy Intense Pink, Fancy Intense Purplish Pink, Fancy Vivid Pink, Fancy Vivid Purplish Pink, Deep Pink and the rarest of all—a Fancy Red diamond,” said Victoria Wirth Reynolds, Chief Gemologist, Tiffany & Co. “Not only are they incredibly rare, but these diamonds also align perfectly with our Diamond Craft Journey initiative, whereby we provide our clients information on the provenance—or the region or countries of origin—for every newly sourced, individually registered diamond that we set in jewelry.”

In celebration of this historic acquisition, the House will present the incredibly rare Argyle Pink™ Diamonds to select clients for a limited time starting in early spring 2023 at global Tiffany High Jewelry events. These remarkable pink diamonds will also appear in carefully curated capsule collections and potentially in future Blue Book creations.

We are delighted that this collection of rare Argyle Pink Diamonds, with their extraordinary Australian provenance and a story that began one and a half billion years ago, are now entrusted to the unrivaled craftsmanship of Tiffany & Co.,” said Sinead Kaufman, Chief Executive, Rio Tinto Minerals.

Due to the unique combination of extreme pressure and temperature required to form these diamonds, they are typically much smaller than 1 carat in size. Among the 35 Argyle Pink™ Diamonds acquired by Tiffany & Co., three are over 1 carat—representing rarity within rarity. Every diamond within the Argyle Pink™ Diamonds: The Tiffany Collection will have both a Tiffany Diamond Certificate and an Argyle Pink™ Diamonds Certificate.
