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. Ruby signifies passion and unbridled, unrestrained love, making a pair of ruby earrings a perfect Valentine's day gift. A pair of created pink sapphire earrings make an excellent gift. Pink gemstones are stylish and chic, and our lab-created pink sapphires are an affordable alternative.
