Why do oxidation of jewelry

I want to know how is jewelry oxidized and why we do it. any advantage? I am allergic to this. Why does it contain any allergic things? What do you mean by oxidization?

I'm not confident that I fully understand your question, Nazish, but some jewelry is indeed darkened or colored by oxidation processes. For example rings may have recessed areas that are blackened with sulfides or other agents, while the highlights are polished.

If you are allergic to these coloring agents, then you'll want to wear only hypoallergenic jewelry, which will probably be a single color rather than having darkened areas.
