Tiny ocean animals called polyps secrete calcium carbonate to create a skeleton, or coral. Over millions of years silica-rich waters replaced the coral’s minerals with agate, becoming a chalcedony (agate) pseudomorph after coral (calcium carbonate).
In 1979, Florida designated agatized coral as the state stone, and many locations for collecting these fossils are now closed. These coral fossils were found in Tampa Bay, FL before the closures, and were part of a private collection until recently.
Each coral is sliced in half to reveal the agate inside. The pair pictured weighs 71.5g and is 65x35x20mm, but we have more in various other sizes. Please choose your Size preference, and we'll pick the prettiest pair for you.
