The Nymph Cartilage Earring is cast in 18-karat gold and features a striking wing cluster pendant, claw set with Australian marquise opal cabochons and a melee diamond. Our cartilage earrings can be worn in multiple areas of the ear, including the lobe, helix, conch, and daith. Note: As Opals are a naturally occurring stone they will differ from what is depicted online, with each being unique.
