A terrific specimen of Smithsonite from the celebrated Tsumeb mine, Namibia. The specimen is thickly adorned with sharply formed spiky crystals measuring to 0.8cm tall. The spiky crystals are arranged in various orientations, formed on a predominantly Galena matrix. The Smithsonites are a lustrous gemmy-translucent white. A very fine specimen of Smithsonite from this classic location.
