The pearl is the oldest known gem, and for many centuries it was considered the most valuable.
Unlike all gems, the pearl is organic matter derived from a living creature - oysters and mollusks
The pearl is an astral stone for the signs Gemini and Cancer, and astrologers link it to the moon. It was said in some early cultures that the pearl was born when a single drop of rain fell from the heavens and became the heart of the oyster. Pearls have been called the 'teardrops of the moon'.
Over time, the pearl has become the symbol of purity and innocence and it is often sewn into bridal gowns, or worn as jewelry by the bride.
There is much folklore and tradition about the pearl. In fact so much history accompanies this stone that five months claim it as a birthstone - February, April, June (traditional), July and November.
