Anodized Niobium is strong, corrosion resistant and hypo allergenic. The colors are beautifully vibrant. The pics are good, but the real-life rings are AMAZING! Our niobium has the same strength as our sterling silver. They are quite similar in terms of workability and quality and look good together.
Anodizing niobium creates an oxide layer. The thickness of this layer creates the colors.
The color will vary from batch to batch. The color will also vary and blend shades on individual wires and in batches of rings. For example, peacock blue can have blue with hints of violet. You can always expect hints of the adjacent colors in niobium spectrum in the batches.
