This single crystal of calcite has a lot going for it and is unique amongst the pieces I was able to acquire. The core of the crystal is gemmy and colorless. The color then turns milky white but, near the termination are several layers of zoned colorless areas. The two edge hex faces sandwich glassy, gemmy, colorless, short prismatic faces which are so gemmy you can look right into, down, and through this crystal from top to bottom. It is complete on both sides as you can see from the front and back views (sticker indicates the back side, to my eye, which has a slight matrix attachment). Very neat crystal!
