Cobalt has now become a very popular metal used as an alternative metal in jewelry for men.
It is especially common in men’s wedding bands, as a great alternative for white gold or platinum. There are so many advantages to this metal that it’s popularity is continuously growing.
Cobalt is mixed with other metals to give it more luster. The highly reflective gleam makes it hard to tell the difference between cobalt and white gold.
It does not tarnish or corrode easily so you don’t have to re-plate like you do white gold. Cobalt is scratch resistant and has minimum maintenance.
