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 Peridot infinity jewelry. A pair of peridot earrings sparkle by day, and remain brilliant at night. The Romans called peridot the “evening emerald†whose vibrant green color remained visible by lamplight. Ruby signifies passion and unbridled, unrestrained love, making a pair of ruby earrings a perfect Valentine's day gift.
