Mokume-gane is actually a "Japanese metalworking procedure which produces a mixed-metal laminate with distinctive layered patterns."  But polymer clay artists can also produce the wonderful multi-colored effect using stacks of different hued clay.  Julie Picarello over on Sculpey demonstrates how this can be done with her awesome Southwestern inspired mokume-gane polymer clay jewelry tutorial.

Her choices of colors and marking tools in her stack really made this design stand out.

I think the trickiest part is making the horizontal slices - the slight variations in how you cut is what gives the layers varying colors.  These thin layers are then added backing clay. So a starting stack can yield many tops.
