Ever wonder where cultured pearls come from? According to ancient Chinese legend, the moon holds the power to create pearls, instilling them with its celestial glow and mystery. In reality, oysters have that power. Cultured pearls are made by oysters with a little help from humans who ensure that conditions are just right to create pearls. Pearls have been treasured for their lustrous, creamy texture and subtle iridescent reflections since the dawn of humankind. Pearls are a June birthstone. As such, cultured pearls are treasured gifts to give to those born in June. Their mothers appreciate cultured pearls, too.
