Rustic hand-forged silver and iron wedding band set. Iron/Silver ring is uncoated. The silver lining is enough to greatly reduce any chance of finger discoloration. The iron is still in contact with adjacent fingers, and may still be an issue for someone with very unfavorable skin chemistry, but probably rare. The linings on the iron/silver rings are fine(99. 9%) silver. Minimum band width 3.5mm.
