RUBY INTERNATIONAL OPENS A NEW MINE IN MERERANI, MANYARA

Mererani is the only place on Earth where Tanzanite is found; and in 2026, Ruby International became part of its story. Our entry into this celebrated gemstone marks the most significant milestone in our growth since Mahenge itself. Unlike some of our other sites, Mererani is worked through underground mining, a reflection of how the deposit sits in the ground and of the specialized care this gemstone demands.

As with every Ruby International site, our approach at Mererani is anchored in responsible extraction, strict compliance with Tanzania’s gemstone mining regulations, and meaningful investment in the surrounding community. Tanzanite’s rarity; found nowhere else on the planet, makes this venture a statement of ambition: to be trusted with a stake in one of the most exclusive gemstone categories in the world.
