12,000 Carat Tanzanite Discovered

12,000 Carat Tanzanite Discovered

TanzaniteOne Ltd. has recovered a 12,000-plus ct. tanzanite, one of the largest tanzanite gemstones ever found, it announced March 1.

The 12,100 ct. rough stone was discovered at the company’s flagship tanzanite project in the Simanjiro district of Tanzania. Initial examinations have indicated that it is the third largest tanzanite recovered by the company and could be the third largest tanzanite stone ever found.

The gemstone will now undergo appropriate analysis, including color and clarity grading. The stone is expected to contain a significant A grade component under the tanzanite classification system. It will most likely be divided into smaller—but still large—pieces to be cut and polished at the company’s in-house cutting facility.
