Fold-over clasps operate on a hinge, similar to the closures on some wrist watches. Pair these with a relatively large loop or jump ring (at least 6mm) at the other end of the bracelet: The clasp hooks over this loop at the the opposite end of your jewelry, then you fold the hinge down to snap the clasp shut. These clasps work great for making bracelets and watches because they can be opened and closed with one hand. The platings on our brass clasps comes in several colors including silver plate, gold plate, copper plate, antiqued brass, and black gunmetal.
On vintage "assembly" bracelets, you'll often find a rhinestone bauble soft soldered or glued to the plated fold-over clasp. Fold-over clasps are still popular on the disk-and-loop bracelets used today, but instead of rhinestone assemblages, we normally see artisan-created polymer clay, dichroic cabs, or cool ceramic pieces glued to the disk bracelets.
