Beautiful clear Green Onyx stones, the color of Columbian Emeralds, are featured on these long marquise wire drop earrings. The stones are about 14mm and the earrings about 1 3/4" in length. Emerald, the birthstone for May, connotes loyalty, friendship and supports the 4th Chakra (Heart) for love and healing. Green Onyx carries those same healing properties. There is no nickel of lead.
