This is a cluster of Beryllonite crystals, a rare berylium phosphate mineral. The crystals are colorless and essentially transparent, although they have a rather rough surface pattern that obscures that transparency. About half of the specimen has a slightly dirty appearance, and is even more difficult to see through. There are a number of tiny tunnels passing through the specimen. While the specimen is clearly crystalline, said crystals are distorted in form, and I cannot describe their shape, other than distorted and complex.
