Niobium jewelry supplies from Rings & Things include ear wires, head pins and jump rings. Because niobium is an inert element, most people with metal allergies can safely wear niobium. It's highly resistant to corrosion and other reactions, and is used in medical implants. By definition, niobium does not contain lead, nickel, cadmium or anything else: It's just niobium.
Niobium jewelry findings come in several anodized colors. Anodized metal is colored by dipping it into an electrically charged "bath" that creates bright colors without plating or painting the surface. The colors don't flake or chip like plated or painted surfaces can.
Niobium Colors will vary: Colors from different batches, especially teal, may not exactly match. Teal ear wires and teal jump rings will look nice together, but are almost guaranteed to be different shades. Raw niobium is a bit grayer than sterling silver or silver/white platings.
