Gold-plated spirals are adorned with sapphire-glass baguettes and pavé centers on this 1950s Duette, Coro’s name for their double clip brooch. It is like a “two for one”! Wear it as a brooch or as separate dress clips. Their double-prong fastener works well with heavier fabrics, such as wool blazers and dresses. The all-diamanté version of this piece appeared in a 1950 Coro ad in Life with the slogan “the perfect jewel of a gift” and with the price of $10.50! (In 1950, the average U.S. family income was $81.48 a week.) You can see the utility patent for the brooch mechanism here, shown below Coro’s name.
