This pendant looks spectacular, but the skills involved are rather basic. I used 14k gold, but it could be made in any metal. I used chasing and repoussé techniques to achieve the look of volume and intertwining. In retrospect, I could have used thicker metal and done the over-under look just by filing. My passion is chasing and repoussé, though, so I look for opportunities to use it. All that's really required is to put the image on your metal and cut out the open sections, first drilling holes to give you a starting point for your saw. Make sure the metal is annealed, or bending the bail at the end will be very difficult, if not impossible. Then cut the outside, making sure to include a tab that will be bent to make your bail. The sawing isn't difficult, but it is a LOT of work. After sawing, use your files to smooth the rough areas, finishing with medium and then fine grit sandpaper. Next, carefully file and sand the "joints" to give the over-under appearance that makes this piece special. Then polish to achieve the finish you want. Now bend the tab to form your bail. Finally, re-polish any area that needs it. I do the polishing before bending the bail because I find it easier than trying to Polish around the bent metal.
