What is Spiny Oyster?
Spiny oyster, not surprisingly, is an oyster that is covered with spines. Like coral or mother-of-pearl, the shell of spiny oyster is considered an organic gemstone. The portion of the shell used to make jewelry is aragonite, which consists of calcium carbonate (CaCO3). Aragonite has the same chemical formula as calcite. Spiny oysters are found along the Atlantic coast of Baja California and Baja Mexico. Common colors vary from orange, found in shallow waters, to red and purple from deeper waters. The shell is also found in white, yellow, pink and brown. Polished shell has definite striations and color variation. Red spiny oyster has been used as a subsititute for coral.
