A new, beautiful bright material, this extremely rare rough comes from a location near the Tanzania/Burundi border called Kibondo. (At least this is what the miners have told us). The color of this material ranges from a very light honey yellow to a deep gray color. Each piece is quite unique. We believe we are presently the only company offering this material in the rough form. This material has a hardness of 6.5.
