Petoskey stones are a type of rock that are found in Michigan, particularly in the northernmost part of the Lower Peninsula and along the shores of Lake Michigan. They are the stone of Michigan and are renowned for their distinctive appearance. Petoskey stones are characterized by their hexagonal-shaped cells, which form a honeycomb-like pattern on these rocks. The cells are often outlined in darker-colored lines, creating a mosaic or "turtleback" appearance. 16” x 16” bag with two 14” long and 1” wide black cotton webbing strap handles.
