These helm earrings are woven with Argentium sterling silver wire that is wound and cut into rings and highlighted with Anodized Niobium teal rings. The earrings hang from handcrafted Argentium sterling silver shepherd hook earwires and measure 1 1/2" from the top of the earwire.
Niobium is one of a group of metals called “Reactive Metals.” This means that is can easily undergo chemical reactions when combined with certain other elements. When niobium is subjected to an electrical current in a bath of water with a specific soap solution, it causes a layer of niobium oxide to form. The niobium oxide is perfectly clear, but changes the refraction of light on the metal. As the thickness of this invisible layer changes, the color changes.
