Description

    TOURMALINE
    Cruzeiro Mine, São José da Safira, Doce Valley, Minas Gerais, Brazil

    Some Tourmaline pockets are filled with "jackstraw" groups of that mineral: a single mass of inter-grown Tourmaline prisms oriented randomly. In this example, olive green prisms, some with pink areas, seem to have been dumped into the pocket, where they continued their growth. Many terminations appear black but are actually a very dark blue color with a peculiar matte luster not seen on the glassy sides of the crystals. Here and there are several small colorless Quartz crystals along with a lot of tiny olive Tourmalines sprouting from protected areas in the interior. There are a number of breaks to some crystals but most are terminated.
    Overall measurements: 6.5 x 5 x 3.5 inches (16.5 x 12.7 x 8.9 cm). Offered at no reserve.

    Provenance: Western Minerals [Hoppel Catalog # D2072]


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