Rio Tinto’s Final Beyond Rare Tender Marks the End of a Diamond Era
Rio Tinto’s third and final Beyond Rare™ Tender, titled The Art Series: Into the Light, has concluded with strong global demand, securing the company’s place in the history of rare diamonds. The tender comes 40 years after the commissioning of the Argyle diamond mine in Western Australia and 22 years after the start of operations at the Diavik mine in Canada.
The 2025 tender featured 52 lots totalling 45.44 carats, including six Masterpieces — carefully curated sets highlighting the pinnacle of production from Argyle and Diavik — alongside 39 single stones and seven matched sets. The Argyle pink, red, and violet diamonds came from the final legacy inventory, making them among the last of their kind.

Singapore-based Argyle Pink Diamonds Icon Partner™ Glajz THG, in collaboration with Scandinavian jeweller Hartmann’s, won the coveted Lot 1 consisting of two Fancy Vivid Purplish Pink pear shapes and a 5.11-carat Flawless D-colour Diavik emerald-cut diamond. “We are delighted to win these extraordinary masterpieces of nature and look forward to honouring the powerful provenance of the Argyle and Diavik mines,” said John Glajz, Managing Director of Glajz THG.
Patrick Coppens, General Manager of Sales and Marketing, Rio Tinto Diamonds, described the tender as a fitting finale: “Presenting this final collection is a wonderful epilogue to Rio Tinto’s inspiring story of mining and marketing diamonds. The world is still captivated by their beauty, exceptional rarity, and pure provenance.”

Since 1985, Rio Tinto has sold approximately 2,500 carats of rare pink, red, and blue polished Argyle diamonds — less than 0.0003% of the mine’s total production — through its annual tenders. With Argyle closed in 2020 and Diavik scheduled to close in 2026, the Beyond Rare™ legacy now enters the annals of diamond history.

Botswana Looks Beyond Rough Diamond Sales, Eyes U.S. Jewelry Market
The Duty Exemption By US Presents An Opportunity For Domestic Jewelry Manufacturers In Gaborone To Bypass Traditional Middle-Market Hubs and Establish A Direct Pipeline To American Consumers
Grappling with a painful downturn in global rough-diamond demand, Botswana is pivoting its economic strategy: expanding up the supply chain directly into American retail shelves while leveraging its resource wealth to fund conservation and diversification.
Speaking on the sidelines of New York Climate Week, Bogolo Joy Kenewendo, Botswana’s Minister of Minerals and Energy, highlighted the southern African nation’s plan to capitalize on a 0% import-tariff rate to the U.S. market. The duty exemption presents an opportunity for domestic jewelry manufacturers in Gaborone to bypass traditional middle-market hubs and establish a direct pipeline to American consumers.
shift The push into value-added manufacturing comes as the world’s top diamond producer by value navigates a broader structural Diamond revenues have long formed the bedrock of Botswana’s post-independence balance sheet, underwriting universal secondary education and tuition-free university funding. However, recent market volatility has underscored the vulnerabilities of a mono-sectoral economy.
Under the Botswana Economic Transformation Programme (BETP)—an initiative spearheaded directly by President Duma Boko and his vice president—the government is directing resources toward manufacturing, agriculture, and broader mining sectors to reduce its heavy reliance on rough diamond sales.
To support its luxury exports, Botswana is recalibrating its brand narrative around origin, environmental stewardship, and social impact. The country recently announced a five-year extension of the “Okavango Eternal” partnership alongside De Beers Group and the National Geographic Society. The initiative aims to protect the ecological integrity of the Okavango River Basin while tying diamond purchases to conservation efforts.
With De Beers currently facing an impending ownership change, officials remain optimistic that any capital restructuring could bring additional funds into Botswana to accelerate its domestic economic transition.
