Tanzanite is a very desirable gemstone due to its catchy vivid violet blue color, transparency and unique shine. It is a variety of mineral zoisite and its findings and use is not historic as it was discovered first in later half of 20th century in Tanzania near hills of mount Kilimanjaro. The name tanzanite was given first by Tiffany and company to this blue color stone in zosite because of its origin which is confined only to Tanzania. Now as Tiffany is a world's top renowned luxuary jewelry brand and tanzanite had the credit to be named from them has somewhere accentuated its value and fame quickely.
Tanzanite has a single origin that is Tanzania so the deposits are very limited making it a very rare gemstone much more rarer than diamonds. The mining is also halted by the government there making it even lesser available now.
Tanzanite comes with special Pleochroism and Trichroism effects which are a signature quality of the gemstone, the term pleochroism means that a stone will show different colors when seen from various directions and trichroism means total of three colors from blue to violet to containing hues of red and orange in them this is due to the sensitivity of the gem to light, its a property of absorbing colors of higher wavelengths in different lightning situations. The largest tanzanite mined so far is a 3.38kg or 16839 carats by miner "Tanzanite One".

A loupe clean to near eye clean stone with very nice saturated violet color dipicting proper pleochroism will pull high rates then a included one also the cutting and polishing quality plays a major role here to bring out color reflecting property of the gem and determines the rate.
