Petoskey Stone Pendant 25mm x 11mm Oval
25mm x 11mm oval Petoskey stone pendant with a Sterling Silver bezel setting on an 18" Sterling silver chain.
This interesting stone is a variety of Calcite. It was formed by the fossilization of an ancient coral, Hexagonaria. The coral lived in shallow waters and today's fossil often includes ancient silt and mud. Petoskey Stones are found on many beaches of Lake Michigan and Lake Huron, as well as in rock quarries from Traverse City to Alpena. The honeycomb patterned stone has a hardness from 4 to 5 and is the official Michigan State Stone.
