Trifari costume jewelry of the late-1930s included Clip-Mates, their version of the double clip brooch. This example features loops of diamanté-encrusted ribbons. The setting is rhodium-plated. This piece can be worn as a brooch (at different angles, as shown) or as two separate dress clips. The photos show a third option: one clip worn as a pendant on a sterling silver chain (which is not included). A white-gold one would also work well. Wear this piece with faux or real diamond studs for an added touch of sparkle. Scroll down to see a selection of coordinating bracelets. You can see the utility patent for the brooch mechanism , shown below Trifari’s name.
