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, we can make them. The rings are measured ID (inside diameter). Niobium is a rare inert metal so it 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 hypoallergenic nature is not changed. They do not contain nickel or lead.
