Specimen # 230105

Specimen Locality: Sham Rock Shell Mine (Rucks Pit), Okeechobee County, Florida

Mineral Description: A fantastic example of the world-famous calcite-filled clams from Florida. These were Mercenaria (clam) shells which were buried in a sandy shell deposit and died in life position (as closed clams). The groundwater flowing through the deposit over the last million years or so has caused other shells to dissolve, re-precipitating calcites in the void inside of the shell. The gray matrix is the host rock. These are fluorescent AND phosphorescent. Height: 11 Width: 9 Depth: 4.5 cm
