Solid sterling silver and Petoskey stone
Approximately 1.6 inches in diameter, stone is about 0.5 inches across
 
Petoskey stones are a fossilized coral most often found in Lake Michigan.  The vast majority are found in the Little Traverse Bay region of Lake Michigan near the towns of Petoskey and Harbor Springs, Michigan.  It is Michigan's state fossil.
 
Petoskey stones vary in color and pattern.  Your necklace will be unique and the stone may not look exactly like these.  I work with a local stone cutter and choose only the best.  
 
This pendant comes with a sterling silver chain, please choose a length.  I have included a reference photograph.  My favorite chain length for this pendant is 20 inches.
 
Enjoy!
