Orange Spiny Oysters only live in the Mexican Gulf of California seas.  Graduated disk shaped beads, vibrant chip American turquoise, purple clam shell beads and Balinese sterling silver beads combine to make a 20-22 inch adjustable length necklace.  A large 18 mm sterling silver lobster clasp and sterling silver chain were used.  Matching earrings are sold separately but show so you can see how the set looks together.
