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.

Panjshir emerald industry surges, demand drives record $6.1m in gemstone sales
For a country impoverished by years of war and burdened by international sanctions, the trade in precious minerals is a valuable resource, especially in the remote corner of northeastern Afghanistan.
The Panjshir Provincial Directorate of Mines in Afghanistan today announced record-breaking growth in its gemstone sector, driven by strong international buyer demand and increased regional extraction activities.
Following its 23rd successful public commercial auction of the year, cumulative emerald sales in Panjshir have reached nearly 400 million Afghanis ($6.12 million USD), marking a steep year-over-year increase in trade revenue. The latest auction saw close to 3,000 carats of high-grade emeralds awarded to competitive regional and international bidders.
Strong Market Fundamentals & Regional Economic Impact
The Panjshir gemstone sector continues to serve as a pivotal economic engine for the region:
- Workforce Expansion: Over 15,000 workers are currently employed across artisanal and small-scale operations throughout the Panjshir Valley.
- Uncapped Resource Potential: Provincial authorities have identified more than 2,000 prospective mining sites suitable for immediate modern development and investment.
- Macroeconomic Contribution: Boosted by mining rights auctions and natural resource commercialization, total state revenue saw a 22 percent year-on-year surge entering Q2 2026, according to World Bank metrics.
“Panjshir emeralds are globally recognized for their exceptional purity and cut quality, securing a premium valuation across international markets,” said Ghulam Mustafa Habibi, a prominent regional gem merchant.
Strategic Strategic Partnership & Infrastructure Opportunities
To further modernize extraction and capture downstream value, local leadership is actively courting foreign direct investment and technical partnerships. Recent regulatory agreements have attracted venture capital and technical stakeholders across Asia and the Middle East to develop Afghanistan’s broader mineral portfolio.
Strategic priorities for the sector include:
- In-Country Processing Infrastructure: Establishing a centralized processing and standardization hub in Kabul to refine raw gemstones prior to export.
- Modernization & Modern Equipment Deployment: Transitioning operations from traditional manual extraction to industrial-grade technology to maximize yield and operational safety.
- Global Market Integration: Developing direct supply pipelines to major international gem-cutting and retail hubs.
