A beautiful and very unique stone found only in the northern part of the lower peninsula of Michigan. It is composed of the fossilized skeletons of colony coral which lived their lifespan in the warm sea waters that covered Michigan during the Devonian period of time, some 350 million years ago. Each small hexagonal chamber of this unique stone is a section containing the prehistoric remains of a salt water marine life.
Petoskey Stones cannot be polished by using a tumbler. They must be polished individually using a series of either diamond or carbide belts in a step by step process. I start with a 100 grit wheel to get the imperfections out of the stone and then graduate through 4 more grits of belts to the final polish which is done by buffing with two different grits of polish. Each stone must be done individually.
