Loose Tanzanite Gemstone
The most important gemological variety of Zoisite is the Tanzanite. It owes this name to its place of origin, Tanzania, still the place of the only deposits found.
Tanzanite is a precious stone that has recently entered the market. Tiffany & Co was the first company to, thanks to a great marketing campaign, introduce it to the international market.
Because it is only mined in a particular area of Tanzania, deposits are likely to be depleted within a few decades.
