Beautiful Black Charlevoix Stone Pendant. This particular Charlevoix stone has a beautiful shiny black coloration on the front with a gray coloration on its sides and back. Charlevoix stones, like their cousin the Petoskey stone, come from coral that has been extinct for 350 million years! Charlevoix stones are not nearly as common to find as Petoskey stones. Each handmade Charlevoix stone pendant on this website is found by Greg, and hand polished to a beautiful shine. No two are the same. They are a beautiful stone, and an attention getter. The bails are secured to the stone using very strong E6000 glue. Consider purchasing a 925 Sterling Silver Chain with this item.
