Petoskey Stone Size 9 Criss Cross Ring, hot Sterling Silver

This is a striking hot Petoskey stone specimen, 14 x 10 mm, cut, shaped and polished before being set in this Sterling silver ring.

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

Petoskey stones are thought to be a positive energy stone.
