Our cobalt rings use the same kind of cobalt alloy (cobalt chrome) used to built aircraft jet engines. It is so strong that it would not bend out-of-round and it retains its shape permanently.
Cobalt chrome is harder than stainless steel, therefore, harder to scratch. Although not 100% scratch proof like tungsten carbide, cobalt chrome is much harder than titanium, and all precious metals including platinum, gold and silver.
Cobalt wedding bands will never shatter or crack. Due to the fact that cobalt alloys are malleable, cobalt rings are shatter proof.

Cobalt rings have color comparable to white gold and platinum jewelry. Moreover, since cobalt rings are not plated with rhodium, which will eventually wear off, they will retain its premium white color forever.
