Quartz ''cast'' after Calcite (rare locality)

Item Description

Here we have a rarely seen beautiful display specimen from an area about 60 miles west of Tucson. This attractive specimen features a well-defined hollow "cast" of off-white colored sugary / drusy Quartz which have replaced preexisting scalenohedral Calcite that have completely been dissolved away. The piece is rather three-dimensional, and is notably "hollow" underneath. It should be noted that we have this phenomenon labeled as a "cast", as there is some debate in the mineral community as to whether these should be called epimorphs, perimorphs, or something completely different. If you collect "casts", minerals of Arizona or unique Quartz specimens, do not pass this one up, as they are rarely offered for sale on the market.
