A perfect choice for yourself, or as a gift, our Alexandrite stud earrings feature sturdy cast basket settings and beautiful sparkling gems. 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. 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.
