2 1/4" x 1", 5.7cm x 2.5cm. Excellent specimen! Dendritic Native Copper crystals, on and in clear-white Calcite crystals. The exposed Copper has a coating of Malachite on the crystals, while the copper inclusions in the Calcite remain beautifully unoxidized. This is one of my favorite specimens, and it truly belongs in the pages of a magazine.

Specimen comes mounted and labeled, ready for your display.
