    CUPROADAMITE
    Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto Region (Oshikoto), Namibia

    The Cuprian variety of Adamite arguably reaches the peak of color saturation in Tsumeb material. In addition to being richly colored and showy, many, like some of the ones seen here, are somewhat transparent. Listed on the collection label is Conichalcite, but visual inspection could discern nothing that matches that minerals characteristics. However ... there are three other minerals in association with the Cuprian Adamite: one is dark olive green and probably Olivenite; one is a yellow microcrystalline mineral with an acicular habit - possibly Beaverite; and the last is a brown mineral with crude octahedral crystals - most likely Beudantite. All of which makes this specimen quite a poster child for rare Tsumeb Arsenates. The matrix is a seriously heavy massive black mineral of uncertain identity. Overall condition is excellent, as is the luster.
    Overall Measurements: 3.5 x 2.5 x 1.5 inches (8.89 x 6.35 x 3.81 cm)
    Offered at no reserve.

    Provenance: Western Minerals [Hoppel #D1571]
