Embossed Niobium or Hiirodo Earrings with Opals

Lively Australian Boulder Opals contrast with the rich colors of anodized niobium or Hiirodo copper. The earwires are 18k gold-vermeil, left sterling at the top where they rest in the ear, and they clip closed in the back. The pieces move freely on the wires.
