Niobium is strong, corrosion resistant and hypo-allergenic.
In raw wire form it is a dark silver/gray colour but when anodized colours are amazingly vibrant. These beautiful jump rings must be seen to be believed. A great addition to any chain maille work.
Niobium has similar strength and feel as 1/2 hard sterling silver.
Cleaning Anodized Niobium Rings
Normally Anodized Niobium wont require any cleaning. If you see your colours getting a little dull, just wash in warm soapy water, rinse and dry.
