Scientifically called Spondylus, spiny oysters are members of a super-family that includes scallops. While they are not, in fact, true oysters, they do hold a lot of the oysters characteristics, such as their ability to adhere themselves to rocks in a cement-like fashion. To the common man, these incredible creatures are known as thorny oysters, or more commonly, spiny oysters. They are found primarily in the warm waters of the Sea of Cortez, off the coast of Baja California.
Because of the spiny oyster's watery home, mystics believe their gemstone powers mimic the ocean, with cool comfort and peace from the dark depths of the sea; a spiny oyster is also believed to bring a sense of understanding, patience, and knowing from the rhythm of the tides to their wearers.
