Copper in Gypsum (Urish Coll.)

Item Description

A fine, rich and showy miniature of bright, micro-dendritic copper in a transparent gypsum cleavage from the Mission Mine of Arizona. Old and very choice material. Such windowpane slices with such rich forests of copper inside are seldom available. In person, looking at the internal meshwork, you can see how mesmerizing this is and why it is such a classic. Ex Harold Urish Collection.
