The pieces of these "Halo" earrings seem to float inside a loop of 18k gold-vermeil or oxidized sterling silver. They move when you do! The sterling pieces are textured with shiny, polished patterns. The colorful finish is from anodized Niobium, and the plum red and goldleaf finish is from the Hiirodo patina on copper. Earwires are left sterling at the top (except the goldleaf Hiirodo design which has gold-filled earwires) and they clip closed in the back.
