Rufibach Cleft, Vorderer Zinngenstock
    Zinngenstöcke, Oberaar Lake area
    Grimsel area, Hasli Valley, Bern

    This specimen displays the unique character common to the finest of Swiss "Smokies." To start, the transparency of the Quartz is virtually all facet-grade, with almost no inclusions. The color is the unusual "coppery Swiss version" of brown, with none of the yellow overtones common to Smoky Quartz from other areas. Last on the list of superlative assets is the absolute perfection of form and brilliance of luster that elevate this matrix specimen to world-class heights. It does not hurt that the dark crystals are growing from an almost white granitic matrix, either. Inasmuch as the group has but two minor nicks, one of which is microscopic; this would have to be accorded it near-perfect status. A tag on the bottom with "330" has no apparent relevance to the documentation.
    Overall measurements: 6.25 x 5.5 x 5.5 inches (15.9 x 14 x 14 cm)
    Offered at no reserve.

    Provenance: Keith Proctor, Extracted by the Rufibach Brothers [Hoppel #D1778]

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