Do Tungsten Carbide wedding bands from Kay Jewelers contain Cobalt?
Hey, I have been looking into this with no luck.. every website that sells tungsten-carbide wedding bands seems to stress the negatives of rings that are made with a cobalt (as opposed to nickel) binding. Some include oxidation after wearing for a period of time do to oils from skin.. others include allergic reactions.. My problem is I cannot test these issues without wearing the ring.. and we just bought one (with 90 days to exchange), but wedding isnt for 9 months.. If I knew the Kay/Belden rings were nickel based, it would put my mind at ease a bit.. Can anyone shed light on the situation?
Just call and ask the store. As far as I know they are. Cobalt is the binder for tungsten-carbide regardless of where you buy them. If you are truly worried and the salespeople can’t help you just wear your ring for 30 days and see if you have a reaction.
Several of my co-workers have tungsten bands and I’ve never heard any complaints.
I also know the Kay jewlers here has a lifetime or a 3-year warranty on their rings.
