However, rumors of its depletion have been circulating, leaving many to wonder if this precious stone is still available. In this article, we will delve into the world of tanzanite, exploring its history, mining process, and the current state of its availability.
Introduction to Tanzanite
Tanzanite is a type of zoisite, a mineral species that is found in limited quantities in Tanzania, East Africa. It was discovered in 1967 by Manuel D’Souza, a Tanzanian prospector, and was initially thought to be a type of sapphire. However, after further examination, it was determined to be a unique variety of zoisite, which was later named tanzanite. The gemstone’s distinct blue-violet color is due to the presence of vanadium, a rare earth element that is responsible for its characteristic hue.
History of Tanzanite Mining
Tanzanite mining began in the late 1960s, with the first mines being operated by small-scale miners. The gemstone quickly gained popularity, and by the 1970s, it was being mined on a larger scale. The Tanzanian government established the Tanzanite Mines Limited (TML) in 1971 to oversee the mining of the gemstone and ensure that it was being extracted in a responsible and sustainable manner. Today, TML is still the primary operator of the tanzanite mines, which are located in the Merelani Hills of northern Tanzania.
Mining Process
The mining process for tanzanite is complex and labor-intensive. The gemstone is found in a type of rock called graphite-gneiss, which is extracted from the earth through a process of open-pit mining. The rock is then crushed and sorted, with the tanzanite-bearing material being separated from the waste rock. The tanzanite is then cut and polished to bring out its unique color and clarity. The entire process, from extraction to polishing, requires great skill and care, as tanzanite is a relatively soft gemstone that can be easily damaged.
