46CTS Heart Coral Sheppard Earrings -Pendant MJA 1043

Corals have been growing in the oceans around the world for almost 500 million years.

The corals thrived in warm shallow marine waters and over time were buried in sediments as the land surface was juggled by crustal plate movements or the oceans rose and fell.  Temperature and pressure from   compaction during burial, resulted in those deposits, in time,  becoming rock and part of the present day geological record.
