Niobium is a nickel-free inert metal. It is very resistant to corrosion and other reactions, and is used in medical implants. Niobium is not plated or painted, so will not flake or chip. It is anodized, meaning it is colored by dipping it into an electrically charged "bath." Because it contains no nickel, lead, or other additives, most people with metal allergies can safely wear niobium.
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.
