Polished spiralite fossil comes from the foothills of the Himalayas.  This fossil is about 1 1/2 inches tall and held by soldered sterling silver prongs and bail.  The sterling silver chain is 16 inches long and attaches via a lobster clasp.  Some metaphysics believe that the left handed spiral gives the wearer a special connection to the sea.
