Many Companies sell rings with Cobalt in them and DO NOT disclose this! They do this because it is cheaper and easier to produce.When tungsten carbide rings are made combining tungsten and using cobalt as a binder, they can develop a negative reaction to your skin and are of a lesser quality. They can also be easily scratched. Do NOT trust any rings that COMBINE Tungsten and Cobalt.
