These Custom Handmade Niobium Jump Rings are perfect for your special jewelry creations. This listing is for 100 Peacock Rainbow Jump Rings. Any Jewelry made with these jump rings will be a stand out. Niobium is a rare inert metal so it is hypoallergenic and terrific for sensitive skin. It is also available anodized in 21 great colors. The colored niobium is still 100% niobium...the color is not a coating. We run an electrical current through the niobium which changes the way light bounces off of them. The refraction of the light is the color you see. The chemical composition and it's hypo allergenic nature is not changed at all. They do not contain nickel or lead. If you would like another size or gauge, just tell us. We can make them! We size these using the AWG (American Wire Gauge) and use the ID (Inside Diameter). Contact us with any questions. ►Like to learn a little more? Niobium(Nb) is named after Niobe, daughter of Tantalus. Ore reserves are found in Canada, Brazil, Nigeria, Z
