AGATISED CORAL

Two halves polished

Tampa Bay, Florida

Agatised coral is the official stone of the state of Florida.  It was formed when silica-rich groundwater penetrated ancient coral beds of Oligocene to Miocene age (25-30 million years ago) to form chalcedony, often in the form of geodes.  

They occur in a variety of colours and are often cut and polished.  This is a particularly attractive example.
