Each piece is etched in recycled brass and hammered by hand using a special planishing tool. This hand-hammering technique gives the jewelry subtle facets which catch the light, and makes these pieces beautiful to the eye and distinctive from near and far. The final stage is the plating process. Wild Bryde uses a 14k gold-plate finish. Ear pieces are 14k gold fill. Both a large and small running wolf earrings available. This style is also available in silver with sterling silver ear piece.
