Petoskey Stone Necklace, Sterling Silver retailer

This is a remarkable Petoskey stone specimen cut and shaped into a circle about 25 mm in diameter. The bail and 22 inch adjustable chain are sterling silver.

Petoskey stones are not a natural stone but rather a fossilized coral only found in the northern retailer portions of Michigan's lower peninsula. They are also Michigan's state stone and are over 350 million years old.

Petoskey stones are believed to be a positive energy stone.
