Mokume Gane is one of the most beautiful materials we offer at Patrick Adair Designs. Our luxury grade Mokume Gane is an extraordinary composite of nickel silver, brass, and copper. The unique compositing process combined with the hand faceted finish creates a truly unique ring.    How It's Made:   Oxidation: The brass and copper in this ring will oxidize over time. This means that each ring will develop a truly unique character as it ages. It is normal and can be easily polished. Any oxidation can be avoided by using the included ring wax or removed by giving the ring a simple polish. For these reasons, we will not accept returns for oxidation issues with the ring.     Lifetime Warranty: We offer a lifetime warranty for this ring. If any problems arise with your ring, please do not hesitate to email us and we are more than happy to assist you. Delivery: All our rings are handmade for each order in America. This means that depending on our current order volume your ring could ship the day of the order, or it could take approximately 8+ weeks. If you have a pressing occasion coming up, please contact us, and we’ll do everything we can to get your ring to you in time.
