- Pollone Mine, Pietrasanta, Apuan Alps, Lucca Province, Tuscany, Italy
A fine , sharp thumbnail specimen that can be displayed either horizontally or vertically. It seems to be a floater with one sharp termination atop and one more crude termination (or perhaps a particularly smooth contact) at the left side. It is completely crystallized and striated on all four sides. Stood vertically, or laying flat, it is a superb reference example of this species, which normally can only be had in crumbs.
