If you're talking about "real silver edging", then you must of course, use melted silver, being careful to just dip the shell edges in the liquid silver. This method requires the most costly way of silver edging, and some of the more expensive tools etc. If you're just wanting to make decorative shells, then you can buy an acrylic metallic bright silver paint and a tiny fine line artist brush.
I have added a "silver blush" with Bright Silver Accent or Rub N Buff. Any sort of shell collecting and work is very rewarding as sea shells are already perfectly shaped and naturally formed into the most beautiful bits of art.
Have fun and good luck. Hope this helps.

For just a quick edging of silver sparkle, get some clear finger nail polish with silver flecks in it. It gives great highlights, and you don't have to be too very accurate. Have fun!
