Item Description

A sculptural rare and exceptional "angel-wing" pseudomorph from this obscure South Africa locale, that has produced some fine prehnite, prehnite pseudos and optical calcite from a dolerite sill. Tightly intergrown, lustrous, translucent mint-green prehnite crystals have replaced a 3 mm thick paper calcite crystal. The 2 cm pseudo at the base adds depth and character. Pristine, except for a contact on a lower edge. This piece is a trim off of a much larger specimen. Ex Wouter van Tichelen Pseudomorph Collection. It has a fine provenance, having been in the Ed Swoboba Pseudomorph Collection and the Ed David Collection. Ed was Science Advisor to President Nixon and assembled several world-class mineral collection. A fascinating and rare pseudomorph from several of the more important collections of our time for Pseudomorphs - all three being very good provenance! It is elegant adn beautiful, a thin green blade. Valued $1250
