These custom handmade colorful Niobium Jump Rings are perfect for your special jewelry creations. I make these to order for you so not only are they perfect, they are a perfect creation.
These are 12 gauge (2mm) 3-strand twisted niobium jump rings with an ID of 14.5mm. These feture blue, peach and purple.
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. I 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 nickle or lead.
