Pearl gemstone meaning. 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. There is much folklore and tradition about the pearl.

The pearl is an astral stone for the signs Gemini and Cancer, and astrologers link it to the moon.
