Beautiful teal green limpet shells come out of Gulf of Mexico, freshwater pearl on 18" sterling silver chain. All shells are havested naturally, there may be small chips and cracks as we do not harvest them live, we match them as closely as possible. If having a small crack or chip is not okay, please do not order these. We pack them carefully and wrap them so that they are safe during transport. They are labeled with the following tag "All Shells are harvested naturally and all chips/cracks in shell are part of mother natures design".
