Handcrafted with sterling silver (.925) and copper. Each piece is uniquely textured by using different planishing hammers. Accent pieces are Swarovski crystals or beads. Ear wires are 20 gauge sterling silver or can be changed out to lever backs in surgical steel or Niobium which is naturally hypoallergenic, making this ear wire especially suited for customers with metal sensitivities.
