An exceptionally rich example of this rare phosphate species (Ca and Zn-containing), from the classic locality for collectors if not the type locality itself. Specimens of this quality are few, and I have seen only 3 comparable for sale amidst a large selection of lesser quality and broken pieces over the years. This piece has a protected cavity with acicular crystals to over 1 cm, some of them translucent, most of them sharp and lustrous.
