A Fascinating Gemstone
The discovery of Tanzanite is shrouded in mystery. But one thing is known: it is only found in one place in the entire world, an area no bigger than four square miles at the foot of Mt. Kilimanjaro in Arusha, Tanzania.
Direct From The Mines
From over half a mile into the earth, Tanzanite is extracted in its rough crystal form by local miners. As a United Nations Sustainable Development Goals-compliant company, with priority access to an exclusive mine, you are guaranteed environmentally safe, fair, and conflict-free gemstones from a trusted source.
Our Commitment to Quality
The Tanzanite rough then travels to Jaipur, India to be sliced into preform shapes, heated to bring out its signature blue-violet coloration, then shaped and polished to create the beautiful faceted stones we offer to you. Every finished stone is personally inspected and graded by our in-house gemologists, to ensure only the best pieces of Tanzanite are ready to be set into our one-of-a-kind jewelry.
