Choose Ruby International Limited for unparalleled expertise, reliability, and ethical practices in the gemstone industry.
Ruby International began its journey with the Mahenge mine in Tanzania, focusing on top-quality Spinels. Founded in 2013 by CEO Salim Almass, our commitment to ethical mining and quality quickly expanded operations to Tunduru, mining Blue/Yellow Sapphires, Alexandrites, and Green Tourmalines.
To better serve global markets, we opened a gemstone office in Arusha, strategically placed for international trade. Expanding further, we invested in a promising mine in Voi, Kenya, for Green Colored Garnets. This move was part of our strategy to grow across East Africa.
Furthering our footprint, we launched a new project in Tanga for Tourmaline and established a presence in Bangkok, enhancing our international reach. Our recent acquisition in Lenshuku, Arusha, adds to our portfolio of Green Garnets, cementing our position as a leading global miner and gemstone supplier.
From our beginnings in Mahenge to our current international presence, Ruby International continues to innovate, explore new opportunities, and uphold our legacy of excellence in ethical mining and fine gemstones.
Ruby International Ltd is a proud member of the following associations, assuring that our company is internationally recognized and has a strong relationship with the global business networks.
We are recognized for our mining projects across Epanko-Mahenge, Muhuhesi in Tunduru, Mwatate-Voi in Kenya and our most recent new project in Mwakijembe, Tanga.
