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 Opal infinity jewelry. This birthstone of October has a luminosity and glow that makes an opal the treasure that it really is.
