An very impressive, sizable and sharp crystal with great luster and strong color change wit the added feature of a well defined internal color zone stripe that is very rare. Displays great with good clarity, only one very tiny edge chip is noted that is almost invisible to the naked eye, and not visible from the best display side. The most impressive feature is the distinct color changes as this is rotated, The color is an intense blue, then a zoned green, rich purple and from along the c axis a strong red. With good backlight a small yellow zone is also seen. With the costs of even average gem Tanzanite being incredibly high, this is an exceptional piece at a great price.
