The blue and/or violet variety of the mineral zoisite, tanzanite has quickly risen to prominence since its initial 1967 discovery. However, despite this meteoric rise, some within the industry remain unconvinced. This is due in part to the unprecedented levels of sales hype that have been lavished upon the material, but also legitimate concerns about durability and the fact that tanzanite’s blue coloration is almost always induced artificially via the heat treatment of previously brownish zoisite.

Believing that the new material’s species name sounded too similar to “suicide”, it was Tiffany & Co. who re-branded the gemstone in honor of the country that was, and remains, its only source locality. In fact, the world’s entire known supply of tanzanite is located within a single eight square-kilometer area of land in the northern Tanzania’s Arusha region, with production from this sole locality having declined significantly in recent years .
