BIG 219ct Deep Natural Color Tanzanite Crystal

This large beautiful Tanzanite Crystal has a deep violet blue color and very good looking crystal structure. A gemmy mineral specimen with big size, which looks amazing when back lit. I had to heat this crystal because it had a very dark color, so heating not only turned it into a beautiful blue violet color, but also lightened it up a bit. You can see the original natural color in the last photo in hand. A great display specimen for anyone who loves big tanzanite gemstones, jewelry, or crystal specimens. Watch the video to see a high resolution 360° view of this crystal.
