The Value Of Tanzanite

Tanzanite, a rare blue-violet form of the mineral zoisite was discovered in 1967 in Tanzania. East Africa is the only source for these gems and the delivery of high quality materials is limited. The limited supply of solid marketing, which, combined with high prices, sometimes $ 1,000 per carat.

Tanzanite is a beautiful pearl, but surprisingly the huge popularity of mountain people, who originally discovered. Tanzanite in its natural state is a product unattractive brown, blue and purple by heat treatment. It’s not too hard jewel. With 6.5 on the Mohs scale and cleavage with delicate, it is less durable than conventional quartz. But the rich colors of the most beautiful tanzanite gemstone is quite unique in the world, in competition with beautiful blue sapphire.

But not all tanzanite is very valuable. The most important determinants of the tanzanite value, like all colored gemstones are color, clarity, cut and carat weight.But in the case of tanzanite, the color is so important that it outweighs almost all other considerations. Tanzanite is a gemstone type I by the GIA, which means that the sample means Tanzanite classified for normal cleaning. Clarity Sun is rarely a problem with tanzanite. But the choice of colors can be very large because Tanzanite occurs in gold, green and purple and blue. The saturation is highly variable, with some rocks a little dull.

Assesses the quality of tanzanite is very important. Unfortunately, there is no accepted standard for that kind of tanzanite. This may be a surprise, because you often hear people speak of “Triple A” or “Double A” Tanzanite. But these terms have no real definition in the trade of precious stones. Indeed the biggest hit tanzanite miner, a company called TanzaniteOne, a completely different sort criteria by their subsidiarly charitable Tanzanite Foundation. You just paint with words like “extraordinary,” “living,” “intense,” “moderate,” “light” and “pale” color and grade of “violetish blue” or “blue-violet.”

As there is no way to tell the difference, measured for example, between “extraordinary” and “living” to say that this system is unlikely to be accepted by a gemological laboratory. But one of the virtues of this method is designed to explain why some colors higher than other kinds of help. In general, we can say that tanzanite is more useful if the color is more violet than blue, and if the color saturation deeper and stronger. While some buyers may have a purple color, or prefer a lighter vein, the deep blue Tanzanites sell the highest price in the market.
