One of the more dramatic specimens, I call the "mushroom" for its appearance: a complete-all-around purple cap perched on matrix. GORGEOUS translucent color when backlit, like grape juice! For whatever reasons, this piece transmits light more clearly than others and so has a richer intensity, and is probably the better for carving rough as well. But if you cut it, I won't sell it to you! The piece is complete on 3 sides, if contacted on the lower periphery.
