Rio Tinto Unveils Final ‘Beyond Rare’ Diamond Tender- Into the Light
Rio Tinto has launched its final Beyond Rare™ Tender, titled Into the Light, featuring 52 exceptional diamond lots from its iconic Argyle mine in Australia and Diavik mine in Canada.
Part of Rio Tinto’s annual Art Series, the 2025 tender showcases 45.44 carats of rare and vivid pink, red, violet, yellow, and white diamonds. Highlights include six ‘Masterpieces’ sets, 39 individual stones, and seven curated sets. Among the standout gems are a GIA-certified Fancy Red diamond, 12 Fancy Violet diamonds, 76 Fancy Pink variants, two D-colour Flawless whites, and a striking 6.12-carat Fancy Vivid Yellow diamond.
This final tender marks a significant moment, as Argyle ceased operations in 2020 and Diavik is scheduled to close in 2026. “It is hard to overstate the importance of this final collection from two extraordinarily beautiful places on Earth,” said Patrick Coppens, GM of Sales and Marketing, Rio Tinto Diamonds. “We honour the people who brought these rare treasures to the world.”
The Into the Light collection will be showcased in Hong Kong, Australia, and Antwerp, with bidding open until 20 October 2025.

Sotheby’s Withdraws Rare 10-Carat Pink Diamond from Geneva High Jewelry Auction
The $20 million ‘Glowing Rose’ was expected to lead the sale but was removed after discussions with the consignor.
Sotheby’s has withdrawn a rare 10.08-carat fancy-vivid-pink diamond from its High Jewelry auction in Geneva, where it was estimated to fetch around $20 million. The Glowing Rose—a cushion brilliant-cut pink diamond set in a ring—was slated to be the star lot of the November 12 sale but never reached the auction block. The company did not disclose the reason for the withdrawal.
“The Glowing Rose is an absolutely beautiful pink diamond… however, following discussions with the consignor, the lot was withdrawn prior to the sale,” a Sotheby’s spokesperson told. The stone is notable as only the third cushion-cut vivid-pink diamond to appear at auction in the past decade and was showcased in Singapore and Taipei last month in a presentation mount by British jeweler Boodles.
Despite the withdrawal, the High Jewelry sale achieved CHF 29.8 million ($37 million), led by a 4.50-carat fancy-vivid-blue, internally flawless diamond that sold for CHF 4.8 million ($6 million). The event ran parallel to Sotheby’s Royal & Noble Jewels auction in Geneva.
