Mokume gane is a type of Japanese metalworking where different metals are combined to create layers. Mokume gane is created by forging together different precious metal layers, such as gold, palladium, and silver, which are then twisted and hand worked into stunning patterns. Mokume gane can be used in men's rings either as a solid band or as an inlay or sleeve in another metal such as Damascus Steel, titanium, black zirconium, or even Elysium Black Diamond.
