These unique hoop earrings begin as narrow copper washers that were refined, dangling with the overlay of an adventurine gemstone and copper bead charm. The copper has an antique patina, sealed with Renaissance wax for stable finish. Niobium allergy free ear wires have tiny copper accent beads. Earrings measure almost 1 1/2” from the top of the ear wire. Hoops are 7/8” in diameter.
