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.

WGC REPORT–Gold Demand Trends Q3 2026
Year-To-Date Demand Of 3,881t Virtually Matches The 2025 Record, While Its Value Has Reached A New High Of US$566bn
Total gold demand, including OTC investment and stock changes, was 1% lower y/y at 1,369t. Year-to-date demand of 3,881t virtually matches the 2025 record, while its value has reached a new high of US$566bn.
Key Highlights
Central bank buying jumped to 321t in Q3, led by China and Poland. The strong quarter lifted year-to-date demand to 675t, 6% ahead of the same period in 2025.  
Global gold ETFs added 211t in Q3, in a sharp reversal from Q2 outflows. Broad-based buying took holdings to a record 4,256t and generated a record US$31bn of quarterly inflows.  
Bar and coin investment fell to a four-year low of 268t. Rangebound prices discouraged fresh buying, although year-to-date demand remained at a 13-year high.  
Gold jewellery consumption fell 17% y/y to 313t, the weakest third quarter in our data series. High prices constrained affordability across all markets, but the value of demand edged 2% higher to US$43bn.  
Total gold supply slipped 1% y/y to 1,369t. Record third-quarter mine production of 1,071t was offset by an 8% fall in recycling to a three-year low of 314t.  
2026 Outlook
We expect continued gold ETF inflows and resilient bar and coin buying, together with robust central bank purchases, to be the principal drivers of overall demand growth. Technology demand should remain firm, but elevated prices will continue to weigh on jewellery volumes. Mine production could reach another record high, but subdued recycling is expected to result in a modest decline in total supply.
