    PARAIBA TOURMALINE

    Very Fine Gemstone: Cuprian Tourmaline (Paraiba Type) - 26.54 Ct.
    Alto Ligonha, Mozambique

    The terms "Paraiba" and "Paraiba Type" are often assumed to mean that the gems have to be blue in color. In actuality, these terms indicate the presence of Copper in the Tourmaline crystal structure. Some of these Cuprian Tourmalines show colors very different from the commonly accepted ones. The modified trillion, seen here, is an excellent example of just such a departure from the norm. The eye clean stone could almost be mistaken for an Amethyst, were it not for the slightly warm cast of the purple and the greater brilliancy of reflections from the interior. The rough was found sometime around 2004, but no other data as to its cutting history is available. It comes with AGL Cert # CS 65930 which affirms its Mozambique origin and, although such stones are regularly heat-treated, this particular one shows no signs of such treatment. A truly unusual and sizable Cuprian Tourmaline.
    Measurements: 22.68 x 18.36 x 12.76 mm, 26.54 cts.
    Offered at no reserve.

    Provenance: Rainbow of Africa Collection
    Accompanied by AGL Certificate # CS 65930
