This is a superb, really top-quality miniature of this extremely rare zinc phosphate species, from the premier (and type) locality. It occurs only in half a dozen places on earth, but here the crystals are biggest and best. This particular specimen is composed of a pleasing and sculptural arrangement of elongated sheaf-like crystals. For the size, and for aesthetics, it would be hard to beat. Generally, as a side note, most of this material dates to the 1960s or prior (the mine was open from 1906 till 1989) .
