    Description

    VIVIANITE
    Huanuni Mine, Huanuni, Dalence Province, Oruro Department, Bolivia

    When Vivianites are first brought out from the mine, they are pretty close to colorless, but exposure to daylight causes them to darken to a deep, transparent green with blue overtones. Old specimens can appear almost black. Although material from the Cameroon is far larger, the Bolivian material is quite superior based on crystal perfection, luster and transparency. This beautiful Bolivian crystal is artfully perched on its sulfide matrix, the better to show off the brilliant luster and dark, Tsavorite green color. There is a small amount of 'contact' but overall condition is quite fine.
    Overall measurements: 3 x 4 x 1.5 inches (7.6 x 10.2 x 3.8 cm). Offered at no reserve.

    Provenance: Sunnywood Collection [Hoppel Catalog # D2098]


    [Scale: 1 inch, with mark at 1 cm]
