Wyatt Signet RingGold plated brass hand carved signet ring Merewif gold plated jewelry is 100% brass with sterling silver ear posts beneath the gold plate. We use a much thicker gold plate than the industry standard, and once the pieces are plated, a protective finish is added to prolong the life of the gold plate. There is no nickel in any of our materials. Do not use jewelry cleaner on plated items. You can polish these pieces with a damp cloth.
