Copper in Gypsum (Kassionas Coll.)

Item Description

Copper in gypsum specimens are a highly desirable, rare and old Arizona combination classsic. This fine, rich and showy specimen of bright, micro-dendritic copper in a sawed, transparent, gypsum cleavage is from the Mission Mine. Old and very choice material. Such thick windowpane slices with such rich forests of copper inside are almost never available! In person, looking at the internal meshwork, you can see how mesmerizing this is and why it is such a classic. Similar sold when we had them in a previous old collection, for $400-500. Ex John Kassionas Collection. Rare on the market!
