We offer a lifetime warranty for this ring. Our rings are built to last a lifetime but we understand accidents can happen. If any problems arise with your ring, please do not hesitate to email us and we are more than happy to assist you. Superconductor is composed of titanium-niobium and copper. The copper may oxidize overtime, forming a natural patina. Each Superconductor ring will exhibit a unique set of patterns. Some rings will expose more or less copper based on ring size and width. We will not replace Superconductor rings on the basis of the patterns differing from the website photos.
