This unique, plain Cobalt chrome 6mm comfort-fit wedding band features a high
polished finish for a more traditional yet modern appearance.
Cobalt is a hard, resilient, hypoallergenic metal with a perpetual
high-luster that is 4x stronger than platinum, 5x stronger than gold, and 7x
stronger than silver. Because of this tremendous abundance of strength, it is
shatter-proof and also scratch-resistant.
