Add a punch of color to your wardrobe. Red Spiny Oyster and sterling silver make this 22" necklace a must have. Spiny Oyster is a shell primarily found in the warm waters of the Sea of Cortez, off the coast of Baja California. Native American craftspeople began using the stunning shell in their jewelry making after seeing the vibrant colors available. The polished shell pieces are accented with 7 handmade sterling silver tubular beads and finished with a sterling silver clasp.
