Genthelvite (rare - classic locale)

Item Description

Genthelvite is a rare zinc-beryllium silicate, with probably the finest examples coming from the famous Poudrette Quarry. This a very fine complete floater thumbnail, with multiple sharp translucent pastel-green crystals to over 1 cm in size; and just a superb example of this very rare species from a single pocket collected about 10 years ago, that features unusually large, unusually translucent, unusually pretty crystals. Valued at $350.
