The technique for Precious Smudged Stone has great results!
Emboss an image you want to use in black ep. Then, take a metallic pad (I have always used gold) and dab it all over your embossed image. Take reinkers (2 coordinating colors) and drop 1 or 2 drops of each on your paper, then rub them into the design (use rubber gloves).
After the reinkers are rubbed in, take a paper towel and buff the embossed image. The colors will be mixed with the pigment metallic ink which acts as a resist.
It is hard to describe, but this is a technique I learned from subscribing to a "Technique Junkie" newsletter from the website
