This may just be a starting place for identifying this mark which looks like H & S along with a hexagon to me, but Hoover and Strong make jeweler's findings, and the company has been in the precious metals business since 1912. Hoover and Strong can be searched online, and their company has contact information. Good luck if you choose to follow this route.
