Characteristics of tanzanite

Tanzanite is a completely new gem: it was first discovered only in 1967 in Africa (Tanzania). Tanzanite got its name from the place where it was found.

However, this gemstone was immediately highly valued: ordinary tanzanites cost $300-400 per carat, while the best quality stones can reach up to $700-1000 per carat.

Outwardly, tanzanite is very similar to the gemstone sapphire, although it is a variety of zoisite. The color of tanzanite is blue or purple. However, tanzanite has its own unique characteristics: when viewed from different angles, this gem changes its color from blue to purple. And under artificial lighting, tanzanite acquires an unusual reddish-violet color.

Not having time to appear on the jewelry market, tanzanite immediately began to be actively bought up, so it even surpassed such well-known stones as emeralds and rubies in sales. Tanzanite has only one significant drawback - this stone is quite difficult to find (and in Russia - almost impossible), there is too much demand for it and too few tanzanites go on sale.

However, having a piece of jewelry with tanzanite, you can effectively stand out, because tanzanite is not only a rare stone, but also very beautiful. In addition, tanzanite has unique optical effects that are hard to ignore.

How much is tanzanite

Small tanzanites up to 1 carat are valued no more than $60. Stones over one carat are valued at between $80 and $150. Stones of 2-3 carats can cost between $500 and $600 per carat. Large stones over 5 carats of the best quality are valued very high - $ 2,000 per carat and even higher.
