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.
In a clear sign of the growing strategic importance of lab-grown diamonds for technological applications, the Spanish government has committed a massive EUR 750 million (approximately $813 million) investment to Diamond Foundry’s new manufacturing plant in Trujillo.
This significant funding injection is specifically earmarked for the production of semiconductor-grade, lab-grown diamonds. It dramatically boosts the project’s war chest, adding to the initial EUR 80 million in funding that the European Union had already pledged last December.
The Trujillo facility is poised to become the largest of its kind in Europe, specializing in high-tech, industrial, and semiconductor-grade diamonds.
- Projected Output: When operations begin—anticipated sometime between 2027 and 2029—the plant is expected to yield over 4 million carats annually, with production slated for substantial increases thereafter.
- Total Project Value: The full cost of the Trujillo project is reported to be a staggering EUR 2.35 billion.
This monumental investment underscores a key trend in the lab-grown diamond sector: a heavy pivot away from the jewelry market and toward high-value industrial and technological applications.
