Durable and affordable, a pair of blue topaz earrings are an excellent gift for a woman with blue eyes, or anyone who enjoys the beautiful color of blue topaz. 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. Sunny and affordable, citrine earrings look perfect when set in glistening yellow gold mountings. Traditionally, citrine is given on anniversaries but is perfect for any occasion.
