Spiny Oyster and Turquoise Necklace
Spiny Oyster is a hinged mollusk that adheres to rocks, coral, and even shipwrecks deep in the ocean. There are several species of spiny oyster, which are highly valued for their unique and colorful shells that range from orange to purple to red. These shells are made into art pieces and jewelry, and spiny oyster artwork has been found dating back five thousand years. Ancient civilizations even used the shell as currency. Todays jewelry almost always pairs spiny oyster with turquoise.
