It is very rare to find strontianite in sharp, hexagonal crystals, and this excellent and very rich example from this classic old locale is exceptional for this reason alone even if they weren't also so pretty to look at. The largest crystal is 2.3 cm and is doubly terminated. The lustrous, translucent, colorless prisms are richly and aesthetically strewn on a maze-like, box-work matrix with sparkly dolomite. Ex.
