Ruby signifies passion and unbridled, unrestrained love, making a pair of ruby earrings a perfect Valentine's day gift. 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. 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.
