Description

Massive Smithsonite pseudomorph after Goethite pseudomorphed after Gypsum! Some of the remaining Goethite is visible at the base of the specimen, otherwise all the piece is thick Smithsonite. Beautiful crystallization at the front but also at the back of the piece with rice type Smithsonite tiny crystals aggregates! Very aesthetic Aragonite on top crowning the specimen! Quite interesting is the dendritic print starting from the dark top oxydized part and finishing at the center of the piece!
