Description

Superb Goethite specimen with aesthetic stalactite like growth formations, with some irridescence and color contrast at some points, contrasting with opaque white Aragonite crystals scattered sporadically, even on top of these Goethite growth! The best part of the piece is of course the hollow and huge pseudomorph of Gypsum that left its print quite heavilly on this excellent specimen!
