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.

Cartier Reimagines an Icon: The Ruby-Set ‘Juste un Clou’ Debuts for Lunar New Year
A Fusion of Industrial Rebellion and Festive Elegance Marks a Limited-Edition Celebration of Luck and Prosperity.
In a bold intersection of high-fashion defiance and cultural tradition, Cartier has unveiled a limited-edition interpretation of its legendary Juste un Clou collection. This special release sees the iconic “nail” silhouette transformed with a festive row of vivid red rubies, launched specifically to commemorate the Lunar New Year.


Originally conceived in 1970s New York by designer Aldo Cipullo, the Juste un Clou has long been a symbol of the “rebellious spirit” and the elevation of the ordinary into the extraordinary. By integrating rubies—stones that traditionally symbolize luck, vitality, and renewal—Cartier effectively bridges its radical Western design heritage with the deep-rooted values of the East.
The collection features the signature wrap-around nail design in gold in bracelets, necklaces, earrings & rings with the “head” and “point” of the nail meticulously pavé-set with high-quality rubies. Industry experts view this move as a strategic masterstroke, as the “festive red” aesthetic continues to be a primary driver for luxury consumption during the spring transition.
