My daughter and I just finished making these niobium clasps. They come in 11 colors – which is your favorite: pink, purple, yellow brass, vintage bronze, green, steel blue, blue, dark blue, black, peach, peacock rainbow? Mine is BLACK!
Niobium is hypoallergenic; recommended even for the most sensitive skin! The hand anodizing process adds color by creating a refraction of light using a electrical current. It does not change the Hypoallergenic properties of the Niobium. It does allow me to add the most amazing glowing colors.
