This astonishing, three-dimensional, cabinet-sized cast is almost completely covered on both sides by a highly-crystallized, glittering druze of sharp prismatic Dioptase crystals that reach up to a respectable 2.0 centimeters. The largest and best-formed of these crystals are presented on the front side of the specimen. As an accent to the Dioptase's rich emerald-green color, small crystals of brilliant white Calcite are scattered across the front side of the specimen. There is a small pocket of negative space on the specimen's interior and small patches of bright green Malachite covering some of the Dioptase crystals. This piece comes with a custom acrylic base.
