Artcarved Rings Tungsten Carbide Rings?

Tungsten carbide rings? - artcarved rings

My friend and I ordered the wedding and decided to tungsten carbide. I have a tendencey develop a rash of cheap jewelry or watches and earrings to silver, gold or even for sensitive ears, so they are not infected. I know that some carbide rings best use of cobalt in the production process, which can cause irritation of tungsten. We buy "ring" Artcarved brand that should not be using this method. They consider it possible that I will have a reaction? Any information would be very grateful!
