niobium jewelry wire
Niobium is a member of a small family of metals known as refractory metals. All the color you will see is purely refracted light; no dyes, colorings, or paints are used! The thickness of the oxide determines the color you see and allows us to express design in color and pattern. We use an electrochemical oxidation process (water and electricity) to control the oxide build-up and therefore control the color.
Niobium is totally hypo-allergenic. This refractory element (along with Titanium) is frequently used in artificial joints, plates, pacemakers and dental implants. It is the safest metal you can wear.
