Masking Technique for Jewelry with Irregular Shape and Cutouts

My jewelry piece (a brooch) cast in 18K is irregularly shaped and has numerous cutouts. I would like to mask the inside and outside irregularly shaped edges of the piece in order to sandblast the body of the piece and leave the edges highly polished. Is there any technique that I, as a small independent jeweler, can use to mask clean, straight polished edges about 1 mm in width?

THANK YOU,

You can use ordinary masking tape to mask for sandblasting. You may want to practice on a piece of scrap first. You can expose only a part of the brooch at a time so that your pieces of tape are not be too small and wrap tape around to the back of the brooch for security.
