Garnet has been known as a gift of love since the time of the ancient Greeks. A pair of garnet earrings are an excellent gift for an anniversary or January birthday. A pair of black onyx earrings are an affordable and elegant gift. Always appropriate and always in style, black onyx should be in every jewelry box. 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.
