Calcite in Mercenaria Permagna from Ruck's Pit Quarry, Fort Drum, Okeechobee County, Florida USA
This fascinating specimen formed when gemmy calcite crystals grew in the natural pocket formed by a buried fossil clamshell. The interior of the shell is now completely covered with transparent golden calcite crystals. The calcite crystals are scalenohedral form, and are cupped perfectly by the shell.
