Like coral or mother-of-pearl, this vibrant shell is an organic gemstone crafted from the shell of the thorny or spiny oyster. This decorative shell is polished to display striated shades of red, orange and purple.
The spiny oyster is a bivalve mollusk that originated during the Mesozoic era. One mineral component of spiny oyster shell is organic aragonite. There is evidence that the fossilized shell of this sea creature was used for decoration and trade dating as far back as 5,000 years ago. Today, spiny oyster can be found from the coasts of North Carolina to Brazil. This vibrant polished shell is frequently used by Native American artisans in place of coral in silver jewelry. While red is the most abundant color, spiny oyster can also appear is shades of pink, brown, yellow, orange, purple and white. We are proud to bring our customers affordable spiny oyster shell jewelry, featured in our Santa Fe Style and Royal Bali Collections.
