Gold-plated spirals are adorned with sapphire baguette glass stones 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 fur clips. The all diamanté version of this piece appeared in a 1950 Life Coro ad 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.
