This is a very old specimen from the noted classics collection of Phil Scalisi, featuring floating crystals of bournonite replaced by the related lead sulfide species, bindheimite. The crystals are mostly doubly-terminated, and show classic bournonite form! Admittedly, "wolchite" isn't the most beautiful pseudomorph on the planet but its still an impressive piece for intellectual interest and for this old locality, an ancient iron mining area located near St Gertraud. I had only ever seen smears and broken bits of such crystals, and compared to them this is a kingly specimen. ex Harvard University Museum

Bournonite is very rare at this locality. This is a solid , bright metallic mass of galena crystals to 2 cm across, with varying luster from satiny to splendent. Scattered on the galena are lustrous and translucent, light pastel-purple fluorite crystals, to 1.8 cm across. Small bournonite crystals, exhibiting the classic cog-wheel pattern so desirable, are present on some galena crystals, and reach 1 cm across. Additioinally,there are pods of splendent, brassy yellow, drusy, pyrite. A neat combo specimen, from this old classic locale !
