This is one cool natural untreated Tanzanite rough top cabochon. It's a luscious blueish purple.
Now this is not gem quality but this makes a fabulous pearlescent focal cab of natural purple.
19mm wide tapering smaller x 33mm L x 3mm to 4mm height of the polished sides and bottom is polished too.
Tanzanite is only found in one place -- in limited mines at the foot of Mount Kilimanjaro in Africa.

Most all Tanzanite has been heated to change it's color. This is standard in the industry. Except for the very small percentage of Tanzanite that has been naturally heated by mother nature, Tanzanite comes out of the mine as a reddish brown color. It's then heated to bring out this amazing blueish purple color that can go more blue or more purple.color!

About the World's largest Tanzanite:

The world's largest faceted Tanzanite is 737.81 carats.[9] One of the most famous large Tanzanites (242 carats) is the "Queen of Kilimanjaro". It is set in a tiara and accented with 803 brilliant cut Tsavorite garnets and 913 brilliant cut diamonds. The piece is part of the private collection of Michael Scott, the first CEO of Apple Computers.

About Heat Treatment:

Since heat treatment is universal, it has no effect on price, and finished gems are assumed to be heat-treated. Tanzanite is sometimes found in other colors, such as green, although technically it would be called 'green zoisite' rather than Tanzanite.

One of the Metaphysical properties:
Mentally, there are many ways in which Tanzanite can be helpful to one’s life. It has the power to transform negative energies into positive ones. It assists in manifesting your own self rather than being influenced by others or trying to conform to the norm.
