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. A pair of peridot earrings sparkle by day, and remain brilliant at night. The Romans called peridot the “evening emerald†whose vibrant green color remained visible by lamplight. 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.
