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 sapphire earrings set in yellow or white gold is a classic, and is always appropriate. Choose from genuine sapphire, or the more affordable lab-created gem. 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.
