This 1940s Duette (Coro’s name for their double-clip brooch) looks like folded fabric crowned with jewels. It is made of rose-gold-plated sterling silver edged with diamanté accents. At the center of each side is a row of amethyst-glass navettes topped with a row of diamanté. This piece, which was created for the company’s high-end line, can be worn as a brooch or as separate dress clips. Their double-prong fasteners work well with heavier fabrics, such as wool blazers and dresses. My camera picked up two stones that appear to be a different shade of purple, but this difference cannot be seen by the naked eye. You can see the utility patent for the brooch mechanism here, shown below Coro’s name.
