You can almost smell the sweet tartness of fresh blueberry pie when you see our new niobium jump ring mix called Blueberry Fields. These custom handmade niobium jump rings are freshly anodized in this amazing color mix. This listing is for 100 in your choice of gauge and diameter in this palette reminiscent of berries on the vine.
We offer our most popular sizes here but we can make the rings you need. Let us know if you would like another size or gauge. The 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.
Materials: does not contain nickel or lead, surgical grade niobium wire.
