RaSifiwa Gems

RaSifiwa Gems is our gem lab based in Arusha, Tanzania. We source, cut and treat the tanzanite under a single roof. This is the only place in the world where the Tanzanite gemstone is found and has been RaSifiwa’s specialty since the 1980s.

The facility was established to help reach the global demand of the Tanzanite, exporting the gem and other local stones to countries all over the world.
