Company History

Zamha Gems emerged from a vision of responsible mining that honors both Tanzania’s natural wealth and its people. Founded in 2022, our company represents a new generation of mining enterprises in East Africa—one that places equal emphasis on gemstone quality, environmental stewardship, and community development. While we may be relatively young in the industry, our leadership team brings decades of combined experience in gemstone mining, sustainable resource management, and ethical business practices.

Our journey began when our founders identified untapped potential in Arusha’s mineral-rich landscapes. Recognizing both the geological promise of the region and the opportunity to establish new standards for responsible mining, they secured exploration licenses for two promising sites and assembled a team of local experts committed to sustainable extraction methods. From these humble beginnings, Zamha Gems has grown into a respected presence in Tanzania’s gemstone sector, known for both the quality of our stones and the integrity of our operations.

In just three years, we have established reliable supply chains reaching European markets, implemented comprehensive environmental management systems, and developed meaningful partnerships with the communities surrounding our mining operations. Each step in our growth has been guided by our founding principles: respect for the earth, commitment to our people, and dedication to exceptional quality.
