Description

    Cuprosmithsonite Epimorph on Tennantite
    Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia

    Tennantite is one of the few minerals that consistently appear in the form of tetrahedral crystals. In this example the tetrahedral forms are somewhat obscured by an overcoat of druzy Smithsonite crystals showing a leaf green coloration due to Copper atoms in the crystal structure. The pyramidal appearing Tetrahedrite is pure black on exposed edges and the largest crystal is about 3 cm (1.18 inches) across. Condition is excellent with the only bruises appearing on the edges of the piece. There is a Willy Israel Collection label indicating that he got it from Clive Queit of South Africa.
    Measurements: 3.8 x 2.8 x 2.5 inches (9.6 x 7.2 x 6.3 cm)
    Offered at no reserve.

    Provenance:
    Rainbow of Africa Collection, ex. Willy Israel Collection


    Estimate: $4,000 - $6,000.
