Special Features

Investment Grade Tanzanite

This class of Tanzanite belongs to the very top 1% mined and is very rarely seen in the market. We specialize in sourcing the few Tanzanite mined that meet this grade using our 40 year relationship with the miners and our proximity to the mines. Out of a thousand carats mined literally 9 or 10 will be of this grade. These colors are extremely rare and their rarity makes them attractive to investors.

Rounds are in high demand and it is easy to see why in this fine piece/. This wonderful 4.20 carat round boasts all the characteristics of the finest Block D genre. A remarkable depth and vividness of color cut predominately on the blue axis leading to a very fine sharp crisp blue in white light and flecked with periwinkle and violet in incandescent light. Flawless clarity and good brilliance complete the package. A fine, rare Tanzanite indeed.
