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. Do you know someone who loves brown? A pair of smoky quartz earrings is a unique and interesting gift for that special someone or for yourself. A pair of created alexandrite earrings is like two gifts in one. Blue-green by day, and purple-red by night, the color change of this gem is sure to please.
