Rare Tsumeb specimen of pink Smithsonite crystals partially coating a metallic grey stalactite of Tennnantite(?), and a significantly long one at that!  The stalactite is fluorescent orange and is possibly Sphalerite. The Smithsonite are gemmy and reach 5mm in size, preferentially coating one side of the stalactite. The stalactite is slightly irridescent. Ex. Carl Acosta collection.

Fine, highly aesthetic specimen composed of glassy, transparent Calcite rhombs included by Malachite. The crystals are sharp, lustrous, and cover both sides of the specimen (a floater). The Calcite are water-clear making this a really bright and sparkly specimen. Areas of Duftite are also present, mostly on the backside. Ex. Carl Acosta, Tizziano Bonisoli  collections.

Fine an undamaged specimen of yellow Mimetite crystals on matrix. The Mimetite have pointed, gemmy terminations.  Excellent color and luster. Ex. Carl Acosta collection.

Large white Tarnowitzite crystals grown on both sides of a thin rock matrix. Many crsytals are doubly-terminated, including the largest one at 3.5cm wide. More sculptural than most with crystals growing in many different directions. Ex. Carl Acosta collection.

Colorful specimen with yellow Mimetite clusters with Malachite. The Malachite occurs as both isolated masses and coating elongated crystals of an unidentified species (Copper?). Ex. Carl Acosta collection.

Single stalactite of translucent green Smithsonite. One of the more uncommon Smithsonite formations found at Tsumeb and I've only ever seen a few of these. The base shows concentric circles of Smithsonite of varying colors. Undamaged (the tip is perfect) and attractive. Ex. Carl Acosta collection (he called it 'the dunce cap').

Golden/green crystals of Adamite on matrix. Large crystals to 1cm in size. Good Adamite specimens are very uncommon from Tsumeb. Ex. Carl Acosta collection.

White rhombs of Smithsonite atop pink and orange Willemite on matrix. Uncommon from a rare pocket. Ex. Carl Acosta collection.

White Calcite crystals atop layers of solid yellow (cadmium) Willemite. The Willemite is bright yellow and translucent. Unusual! Ex. Carl Acosta collection.

Sparkling, botryoidal white Calcite sprinkled with Azurite crystals. The Azurite crystals reach 7mm in size and are sharp with wonderful form. Superb contrast and Azurite on white Calcite is uncommon! Ex. Carl Acosta, David Ziga collections.
