As a treasure from the sea, the pearl often represents the Self for women. Associated with water (unconscious), pearls often represent inner knowledge, insight from out depths.

When Aphrodite, Greek goddess of love, rose from the sea, she carried a pearl in her hand, so pearls can represent feminine wisdom, especially about love and relationships. Dream interpretation of broken or damaged pearls may suggest that you are unable to rely on or trust your feminine instincts and need to do some psychological repair. It is the birthstone of someone born under the sign of Gemini.
