Raw Rocks!!! This is a very rare Petoskey Stone pattern coupled with that gorgeous petrified (million-year-old) mud! This huge stone looks perfect suspended from a silver ring, complimented by Tibetian silver beads and Sodalite gemstone beads, and on a 28" genuine leather lace necklace. This is a stone that I almost kept in my private collection. You will love this necklace!
