In appearance this galena specimen resembles an oreo cookie with galena on both sides of a calcite layer. Intergrown, splendent crystals of metallic galena form the bottom/matrix of this piece, draped by a vein of colorless, sparkling, calcite crystals. Topping the specimen are large, complexly formed crystals of galena, to 2.5 cm in length. The combination makes a dramatic contrast to display the galena, and a true mineral oddity in its overall appearance! This specimen was on loaned exhibit in the University of Arizona Museum for over a decade until my purchase of this collection in 2008. Comes with custom lucite base already made for the specimen.
