This specimen has the largest crystal I have seen from the find, which shows 2.2 cm well-exposed on several sides and obviously continues into the matrix for another centimeter or so, popping out a bit along the front face (maybe it can be excavated more?), making this surely one of the world's largest of species. The crystal is translucent, and is terminated (a bit rough from contact, but it does seem to be terminated). Major for the species! I do not know if gems can be cut from the species, but if it is possible, this would be the piece...
