Rio Tinto Unveils Rare 158ct Yellow Diamond from Diavik Mine in Canada
One of the largest gem-quality yellow diamonds ever discovered in Canada, the 158.20-carat gem is a remarkable find as Diavik Mine nears closure.
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.

Diamond Price Gains In Sept Led By Small, High-Quality Stones
US Retail Demand Strengthened, Particularly For 1–2 Ct (F–I, VS2–SI2) and 2+ Ct Stones. Lower-Quality Smaller Goods Remain Under Pressure From Lab-Grown Diamond Competition.
Diamond prices continued their upward trajectory in September—traditionally a slow month—driven by reduced production and rising demand. Round diamonds consistently outperformed fancy shapes.
US Market & Trading Sentiment: US retail demand strengthened, particularly for 1–2 ct (F–I, VS2–SI2) and 2+ ct stones. Lower-quality smaller goods remain under pressure from lab-grown diamond competition. Holidays in the US, Belgium, Israel, and India temporarily slowed regional trading.
Trade Show Trends (Hong Kong JGW): Show results were mixed: strong demand for finished jewelry and 2+ ct natural diamonds offset weak interest from Chinese buyers and sluggish movement in smaller, low-clarity goods.
Corporate & Supply Restructuring:
- De Beers is set to acquire Mountain Province’s 49% stake in the Gahcho Kué mine under a debt-restructuring agreement.
- Anglo American’s ongoing process to sell De Beers maintains broad market uncertainty, while recent De Beers rough sights indicate cautious buying.
- Petra Diamonds is evaluating strategic options, including potential asset sales.
