Emerald is associated with Venus, the Greek goddess of love and beauty. They say an emerald pendant can protect lovers from unfaithfulness. Yellow gold brings out the bronze and golden colors inside a smoky quartz pendant. White gold will highlight the brown and grey tones of the gem. Either way, you can't go wrong. Garnets have ancient connections with feminine life force. A garnet pendant worn close to the heart is said to promote balance and peace of mind.
