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.

Natural Diamond Council Launches World Diamond Day on April 8, 2026
A new global moment to share the stories behind natural diamonds on April 8.
The Natural Diamond Council (NDC) introduces World Diamond Day on April 8, 2026, a global movement that brings people together through the stories behind natural diamonds.
On this day, everyone is invited to participate, from those who work with diamonds every day to those who wear, gift, or admire them. World Diamond Day is about sharing the personal and meaningful moments that natural diamonds represent.
Across social media, participants are encouraged to post a photo or short video that captures what natural diamonds mean to them, whether it is a milestone, a memory, a piece of jewelry you love, or the journey behind it.
On April 8, simply share your story using #WorldDiamondDay and #NaturalDiamonds to join a global wave of voices celebrating something authentic.
Stories can take many forms:
– Personal moments such as engagements, anniversaries, and heirlooms
– The journey of a diamond from origin to artistry
– Positive impact in communities, education, and conservation
– Design, craftsmanship, and finished creations
World Diamond Day is a collective moment and not a campaign. It is shaped by the people who participate, from personal milestones to the communities diamonds uplift and transform. It is a chance to see natural diamonds through the lens of real people and real stories shared around the world in real time.
In a world where so much feels easily replicated and fast, natural diamonds are enduring symbols of love and connection. Formed over billions of years, they carry memory and human meaning. World Diamond Day brings those stories into view from every corner of the world.
Everyone is encouraged to take part by sharing a story that feels personal and true. Organizations and businesses can also amplify the movement by inviting their teams, partners, and communities to participate.
Worn. Given. Passed down. Never forgotten.
On April 8, the story of natural diamonds belongs to everyone.
