Tanzanite Gemstone- Precious Stone



The name Tanzanite is derived from Tanzania, which is located in eastern African. This is only place that this December birthstone can be found, and it was first discovered in the year 1967. It has been called the gemstone of the 20th century and has been made quite popular by Tiffanys in New York City. When the first glimpse of this brilliant blue stone with purple tones was seen, specifically discovered in the northern Merelani Hills of Tanzania near Arusha, it was quite a sight.

In Merelani today, the search is carried on for the coveted crystals in several, smallish mines, in some cases using modern methods. As a rule, only small grains are found, but now and again the mineworkers succeed in fetching out a larger crystal – to the joy of the mine owners and that of the large number of tanzanite fans.

The tanzanite trade is in the hands of many licensed merchants, mostly on a small scale, who have, over the decades, built up stable, trusting business relationships with gemstone companies in India, Germany, Israel and the USA. An estimated 90 per cent of all tanzanite merchants are official members of the International Coloured Gemstone Association ICA, and are thus bound by the high ethical standards of that organisation. In this way, this exclusive gemstone is not subject to trade via dubious channels, but instead, in spite of its rarity, passed on along reputable trade routes to established cutting-centres and subsequently to major jewellers all round the world.

Common Cuts:
 
Tanzanite gems are most commonly, although by no means exclusively, fashioned into Oval and Cushion cuts. All accepted gem cuts are however available.
