Niobium is a lustrous, gray metal with low toxicity (so low that it is safe even for those with extreme sensitivities to metal jewelry) and virtually no susceptibility to tarnish. Its unique properties as a reactive metal cause niobium to take on a controllable, repeatable range of colors when exposed to various voltages in an electrically charged bath, a process called anodizaton. The colors produced will not rust and cannot be rubbed off, although, over time, its luster may dull somewhat.
Niobium is very slow to work-harden and is remarkably easy to work with. Cut with a jeweler's saw, hand-form, dap, chase or forge the metal easily. In cold working (rolling, forming, etc.), niobium can be reduced as much as 90% before requiring annealing.
