This listing is for 100 niobium jump rings in your choice of gauge and diameter in this palette reminiscent of berries on the vine with the colors of dark blue, medium blue, blue-purple, bright purple, purple-pink, and turquoise. These custom handmade niobium jump rings are freshly anodized in this amazing color mix.
We offer our most popular sizes here but we can make the jump rings you need. Let us know if you would like another size or gauge. The jump rings are measured ID (inside diameter). Any jewelry made with these rings will be a stand out! Niobium is a rare inert metal and is hypoallergenic and terrific for sensitive skin.
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 its hypo allergenic nature is not changed at all. They do not contain nickel or lead.
