Description

A large and superb example of this strange and pretty Florida phenomenon, as this is a complete shell standing up on the natural "base", making it particularly aesthetic! This fascinating specimen formed when gemmy calcite crystals grew in the natural pocket formed by a buried fossil clamshell. The shell is in excellent condition, the details are all still intact and you can see the texture of the shell. A really special one!
