Description

    Prehnite Pseudomorph after Calcite
    Zoetwater, Calvinia, Namakwa District, Northern Cape Province, South Africa, South Africa

    Some specimens are cool, whether you are a dyed-in-the-wool mineral collector or just an aficionado of pet rocks. A top contender in that category is this bit of geological Origami that started out in life as a group of wafer thin Calcite blades that were replaced by pastel green Prehnite that faithfully preserves the arrangement of the preceding Calcite. The largest blade measures a hefty 21 cm (8.3 inches) across but is only 2-3 mm in thickness. There is an accession number on the back: "16D," but no other data. A custom stand has been crafted for this very large, but exceedingly lightweight, cabinet specimen.
    Measurements: 11.0 x 7.1 x 4.9 inches (28.0 x 18.1 x 12.4 cm)
    Offered at no reserve.

    Provenance: Rainbow of Africa Collection


    Estimate: $4,000 - $6,000.
