Switch up your usual cubic zirconia earrings for the beautiful yellow hue of citrine. Made from sterling silver, each earring displays a 3mm round citrine cubic zirconia crystal. Not only do they make a pretty pair, but as citrine is the November birthstone, these earrings are sure to delight as a November birthday gift. Weighing just less than 1 and a half grams, these studs are secured in place by butterfly backs stamped with a 925 metal mark.
