To see a world in a grain of sand and heaven in a wild flower, hold infinity in the palm of your hand and eternity in an hour. -William Blake. Your spirituality is on display with Fire Opal infinity jewelry. 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.
