Tanzanite is the crystalline form of the mineral zoisite and is an exquisite violet-blue gemstone. It is very rare. The zoisite crystals form in the presence of vanadium, which is a soft, grayish-silvery metal. Its crystal structure is orthorhombic and it is Trichroic, radiating three different colors from three different crystal axes.

Tanzanite is found in only one place in the entire world, Tanzania, in the foothills of Mt. Kilimanjaro. The area in which it is found covers only 4 square kilometers.

Considering that Tanzanite can only be found in a 4 kilometer square area and that the top quality colours and sizes are becoming harder and harder to extract from the ground, it is very rare and becoming rarer. Tanzanite is in fact considered to be a thousand times rarer than diamonds.

Tanzanite was discovered in the mid 1960's in the Merelani Hills of East Africa by Massai tribesmen after a bush fire had heated the rough Tanzanite changing it to the stunning intense violitish, blue colour that we know.

Tanzanite is a hydrous Calcium-Aluminum Silicate with a hardness of 6.5 on the Mohs scale.
This means that Tanzanite's hardness is similar to emerald but a bit less brittle and should be cared for. It is not as hard as diamond which rates as 10 or sapphire which rates as 9 on the Mohs scale but harder than steel which rates about 4-5. Therefore Tanzanite should not be worn during activities that may cause impact. Ideally it is set as a necklace, dress ring, earrings or occasionally a bracelet.

Yes. Tanzanite is already one thousand times rarer than diamonds and given that it is only 6.5 on the Mohs scale, many pieces are accidentally destroyed. The fact that it is formed by a unique geological phenomenon, that has less than a million to one chance of being repeated, means that according to geological tests, the world’s supply of Tanzanite will be totally exhausted within 10 to 15 years.

Given the not so hard nature of Tanzanite, it is recommended that a soft cloth and warm soapy water is used to clean it in a gentle and controlled manner.
Under no circumstances should an ultra-sonic cleaner be used.

It is not Likely. Intense geological research has found that there is only one source of tanzanite and it's geology is totally unique. It is a "geological phenomenon" with the chances of another occurrence, outside of the current production area and its immediate vicinity, being less than a million to one.

Tanzanite is the first Gemstone to have been added by the American Gem Trade Association to the list of Birthstones since 1912 and is now an official Birthstone for December.
The Massai Tribesmen give it to all their newborn children as a bearer of good fortune.
It is also said to have many mystical and healing powers. It uplifts and opens the heart. It is a gemstone that shows us a graceful, gracious way to live.
It is said that people who wear it feel spiritual power pulling them up. It also encourages the wearer to help others because it helps them realize that their own individual truth is connected to eternal truths and the two would sustain each other. They are well grounded in truth, nature, and spirituality.
Also it activates the throat chakra for clear communication of one's highest truth and can also be used to enhance psychic abilities.

Tanzanite, given it's desirability and rareness, coupled with it's dwindling supply makes it one of the surest investments of our time.
