This Petoskey is one of my favorite kinds, sorta all over the map with lots of different features but incredible pattern and contrast. Now dubbed the Mosaic Petoskey I set this gorgeous specimin in a sleek bezel to let the stone shine and paired it with a modern geometric band. 
 
Size 7.75 and cannot be resized.
