Medieval art rings are made from copper with silver and black accents. Buy medieval rings with sparkling diamond cuts and fine quality at affordable prices. Adjustable copper medieval rings are about 1.3 cm – 0.4 inches wide in the middle and fit most fingers sizes 6 to 10. No polishing is required as the copper rings are protected from tarnishing with many layers of finishes. We also dip them into lacquer for thicker and better protection.
