This Coro sterling brooch is a pair of flowers with diamanté centers and oval petals, crowned with baguettes, and set in pavé-embellished sterling silver. It was designed as part of the Platina line by Adolph Katz for the company’s high-end pieces. You can wear this one as a brooch or as separate dress clips. The double-prong fastener works well with weightier fabrics, such as wool blazers and dresses. This piece was advertised along with the complete Platina line in a fashion magazine with the copy: “Glittering glamour set in sterling silver with that ‘platinum look’”. You can see the utility patent for the brooch mechanism here, shown below Coro’s name.
