5.55ct Miniature Bi-color Tanzanite Crystal

This tiny, yet beautiful, bi-color tanzanite crystal has an amazing intense transistion from pink to violet at the base of the crystal down one axis. When looking at it from the other angle, it's more of a brownish to blue. This unique tanzanite crysta weighs 5.55 carats and measures 10.8mm x 7mm x 6.9mm. Unfortunately, I can not say for certain whether this crystal has or has not been heated.
