Calcite on Fluorite

A lovely piece of deep amber stacked scalenohedral calcites on a thick shard of purple fluorite. Ross Lilly label states it is from pillar robbing in 1982. Internal cleave near the termination is natural and not visible from many angles. There are two small slightly bruised areas. Ex Jim and Paula Wilson.

Locality: Sub-Rosiclare Horizon, North End, Denton Mine, Southern Illinois

Composition: calcium carbonate on calcium fluoride
