These handcrafted Garnet and bronze Czech bead earrings feature Niobium earwires in a matching bronze finish which add color to the design. The earwire is 99.9% pure niobium (a nickel-free, inert metal). It is colored by dipping in a anodized bath and is not coated or painted. Niobium is very resistant to corrosion and other reactions and is used in medical implants. By L. Rene Designs. Shipping is a flat $2.00 each on all jewelry items.
