Pearl is the birthstone for June.
It is the oldest known gem, and for many centuries it was considered the most valuable. Unlike other gems, it is an organic matter derived from a living creature - oysters and mollusks.
Nearly all pearls sold today are cultured pearls. Freshwater pearls are from mussels while saltwater pearls are from oysters. They are believed to attract wealth and luck as well as offer protection. Known for their calming effect, pearls can balance one's karma, strengthen relationships, and keep children safe. The pearl is also said to symbolize the purity, generosity, integrity, and loyalty of its wearer.
