Rio Tinto has uncovered a rare and exceptional 158.20-carat yellow diamond at its Diavik Mine in Canada, marking one of the largest gem-quality yellow diamonds ever found in the country. This stunning discovery is also among only five yellow diamonds weighing over 100 carats to be unearthed by the company at Diavik throughout its 22-year history. Notably, Diavik is primarily known for producing white diamonds, with less than 1% of its output being yellow stones.

The Diavik Mine, which is set to close next year, is also responsible for several significant yellow diamond finds, including Canada’s largest yellow diamond, a 552.74-carat gem discovered in 2018, and the 187.7-carat Diavik Foxfire found in 2015.

With the closure of the Argyle mine in Australia in 2020, Diavik is now Rio Tinto’s sole diamond asset. Patrick Coppens, General Manager of Sales and Marketing for Rio Tinto’s diamond business, expressed excitement over the unique beauty and purity of the Diavik diamonds, eagerly anticipating the future of this extraordinary find.

GJEPC intensified its promotional efforts in the United Kingdom ahead of IIJS Bharat Premiere 2026 through a week-long outreach programme in London that combined direct retailer engagement with the 2nd India-UK Jewellery Buyer-Seller Meet (BSM). The initiative was held from 6 to 10 July 2026 and aimed to attract more UK buyers while strengthening trade ties following the India-UK Free Trade Agreement.

As part of the campaign, Gaurang Vora, Manager, GJEPC, visited major jewellery trading hubs including Green Street, Southall and Wembley, meeting 20+ jewellery retailers and wholesalers through in-person interactions. He promoted IIJS Bharat Premiere 2026, distributed event information and registration details, and gathered market feedback on sourcing requirements and buying trends.

Based on feedback from UK buyers, the 2nd India-UK Jewellery Buyer-Seller Meet generated strong demand for 22-karat gold jewellery, diamond jewellery, lightweight designs, lab-grown diamond jewellery and silver jewellery. Buyers also expressed interest in sourcing from reliable, export-oriented Indian manufacturers and suggested that suppliers offer smaller minimum order quantities to better meet the needs of independent retailers.

The campaign generated new buyer enquiries, strengthened relationships with existing trade partners and provided GJEPC with market intelligence on consumer preferences and sourcing trends. The Council plans to continue engaging with buyers, assist with IIJS Bharat Premiere registrations and facilitate introductions between overseas buyers and Indian manufacturers.
