Tungsten Rings that are $20.00 or under, you are not going to be happy with them. Those rings are probably made with Cobalt.
What is Cobalt? Cobalt is a cheap way of manufacturing a tungsten ring, make sure you get a ring that is cobalt free.
So how do you know?
Ask the company if they are Cobalt Free or if they are made with Nickel. Make sure the ring you purchase is made with Nickel.
Tungsten Rings made with Nickel, you will be happy for a lifetime!
