VALENTINITE

Crystal Classics Verified independent store

A dense banded mass of fine-grained Sphalerite and possible Galena (or perhaps Native Antimony) displays patches of pearlescent white bladed Valentinite upon the coarsely crystalli zed dull grey sulphide/antimonide. The blades of Valentinite reach 5 mm in length and form aggregates up to 1 x 1 cm in extent but with many smaller patches within crevices. Valentinite is a rare antimony oxide with very few localities known to have produced rich crystals, but the Příbram District is one such area. There is some minor damage to some of the areas of crystals, but this is an old piece and it remains a very rich and significant specimen of this rare species. Show more
