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. Opal symbolizes confidence, clarity, and calmness and is said to promote faith in oneself and hope for the future. Wear an opal pendant to capture these qualities. 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.
