Mokume gane is a technique that joins dissimilar metals together for ornamental purposes. Metals are joined by diffusion bonding to create striking contrast and patterns. There are hundreds of different metal combinations, patterns and techniques to choose from. I chose a textured combination of 14kt red, yellow and white gold. Because all these metals are relatively inert, it provides a comparatively easy example.
I have no formal or informal training in jewelry or silversmithing. However, I have done some blacksmithing, and I study materials science. Don't let that scare you! I will explain the theory behind each step, how to do it, and what to do if things go wrong. You don't need any previous experience to get this right.
This instructable is based loosely on the website I made to catalog how I made the wedding rings. The wedding site reads more like a story than an instructable, which is why I've restructured it for you. You can find the original here: http://www.mike-short.com/MnM/Rings/Rings-Intro.shtml
