    Thunderegg Slice
    Black Rock Desert
    Nevada
    6.53 x 4.52 x 0.40 inches (16.60 x 11.50 x 1.03 cm)


    This rough oval slice, from a nodule-like rock similar to a filled geode, is a thunderegg that formed within rhyolitic volcanic ash layers. There is a double star-shape center of Chalcedony which has been fractured following deposition of Agate. The pattern is remarkable for a natural piece, and the slab, from the Black Rock Desert of Nevada, features unique contrast with one star being hollow, while another is filled solid.

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