This double clip brooch and earrings were sold to me as a set, but my research uncovered a different story. The diamanté-embellished gold-tone Coro Duette is named Merry Whirl, while the gold-tone and diamanté earrings are from their Gay Swirl design. Nevertheless, I wouldn’t hesitate to wear these pieces together. The Duette, Coro’s double clip brooch, can be worn as a brooch (in the positions shown) or as separate dress clips. The earrings are screw-backs. Both pieces were advertised in the April 1948 issue of Life magazine, which is how I found out the design names. You can see the utility patent for the brooch mechanism here, shown below Coro’s name.
