A cute little way to show off small Petoskey Stones! Each 1" x 1" x 1" clear acrylic contains 5 - 8 small Petoskey stones. The rough stones are tumbled down to smooth them out and then fit into each box. The patterns really pop if you get the stones wet just like if you found them on the beach, or for a more permanent "wet" look, you can give them a light coating of mineral oil.  

 Petoskey stone is buffed polished and coated to enhance the beauty of the piece. This interesting stone is a variety of Calcite. It was formed by the fossilization of 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 Travers City to Alpena. The honeycomb patterned stone has a hardness from 4 to 5 and is the official Michigan State Stone.
