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.

Mohar Fine Jewels x Gemfields : From Florals To Geometry, Coloured Gemstones Take New Forms
The Latest Collection Pairs Gemfields’ Zambian Emeralds and Mozambican Rubies With Mohar Fine Jewels’ Craftsmanship Across Bold, Floral and Contemporary Designs.Â
With a three-generation legacy in fine jewellery, Mohar Fine Jewels has built its expertise around natural gemstones, with emeralds being a particular focus for the family. The latest additions to the partnership with Gemfields bring together Zambian emeralds and Mozambican rubies across individual designs that play with floral forms, geometric silhouettes and statement proportions.




The new pieces look at coloured gemstone jewellery through a more expressive lens, with the gemstones often taking centre stage rather than being treated as accents. The Ruby Droplet Earrings, for instance, use 33.69cts of Gemfields Mozambican rubies with 4.78cts of diamonds, creating a bold red statement in 18k gold. On the emerald side, the Emerald and Diamond Blooming Studs bring together 18.30cts of Gemfields Zambian emeralds with 4.07cts of diamonds, translating the idea of a bloom into a more defined, sculptural silhouette.


The Emerald and Diamond Earrings make a statement through scale, featuring 51.59cts of Zambian emeralds alongside 8.96cts of diamonds. A more structured take comes through in the Emerald and Diamond Studs, which pair 7.36cts of Zambian emeralds with 0.965cts of diamonds. Meanwhile, the Emerald and Yellow Diamond Studs introduce a contrasting play of colour, centred around a 25.6ct Zambian emerald with 3.09cts of diamonds. The Ruby Blossom Necklace takes the floral inspiration in another direction, using a blooming silhouette to frame the deep red of Mozambican rubies.
Across the pieces, the designs move between statement and more wearable silhouettes, making coloured gemstones the defining element for occasion dressing while bringing together Mohar Fine Jewels’ craftsmanship and Gemfields’ Zambian emeralds and Mozambican rubies.
