This sleek medieval cross with 24 inch curb chain is designed in solid stainless steel with black IP finish. IP Plating or Ion Plating is one of the newest and most advanced surface finishing processes available in the jewelry business. Ion plating produces a harder and more durable coating with a higher brightness than that produced through traditional plating methods. Experiments have proven that the finish obtained with IP is five to eight times better than that of conventional methods in terms of wear and corrosion resistance. Advanced methods in stainless steel jewelry design offer exceptional quality in both appearance and durability.
