This Mokume Gane is layered with Argentium Sterling Silver and Palladium for a beautiful bark effect that is soft and also discrete. The width is wider for her and much narrower for him but a bigger size finger.  I lined both rings with Argentium Sterling Silver and added an edge of 14K Red Gold to frame the Mokume Gane center.

Note:  Mokume Gane is a Japanese metal technique of layering many times over 2 or 3 different metals of different shade and alloy.  Often Copper is used with gold or silver but I prefer to stay with precious metals, especially for rings, like Argentium Sterling Silver and Palladium, 2 beautiful white metals.
