Niobium is a hypoallergenic metal, so great for those who are sensitive to metals. It is anodised to get these amazing colours. It cannot be soldered, so they just need to be closed up tightly with pliers.
The jump rings are 0.8mm thick and measure 6mm in diameter.
Choose from gold, green, teal, dark blue, purple or pink. We also stock niobium earring hooks in the same colours.
