Realgar on Calcite (Kay Robertson Coll.)

Item Description

Brilliant, gemmy cherry-red realgar crystals are aesthetically clustered along one side of a beautiful, sharp two-toned calcite scalenohedron. The lower portion of the calcite is water-clear, gem light amber with the termination being colorless, translucent. The striking stepped-growth faces really add pizzazz to this cutie. The calcite is 360-degrees, essentially pristine, with only a bit of contacting. Ex Kay Robertson Collection # 12484 and acquired from Scott Williams in the late 1990s.
