Mokume gane is an ancient Japanese technique that bonds many layers of precious metals into a single piece that is then worked into beautiful patterns. The name means "wood pattern metal". My mokume gane is fused by the traditional method, using heat and pressure. Our patterns and designs showcase the natural beauty of the material, and the quality of our rings is second to none. The rings on this page are constructed in the traditional manner Ð a piece of material is patterned while flat, and then shaped into a ring. Chris Ploof Studio is proud to also offer the only seamless mokume gane rings in the world.
