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. 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.
