This vintage Coro Duette with diamante rhinestone flowers, Patent 156895, was designed by Adolph Katz in 1950. The happy little posies have sparkling clear rhinestones that have retained their brilliance beautifully. The heavily rhodium plated settings and Duette frame are also in excellent, near mint condition and belie the fact that this pretty is more than 65 years old. Each flower clip is signed Coro and the Duette frame is signed Coro Duette patent number 179886. This piece looks lovely worn as a brooch and equally striking separated from the frame with each flower clipped independently anywhere you'd like to add a bit of dazzle. I love this vintage piece, it has far more impact than its dainty 2 inches by 1 1/8 inches dimensions would suggest. This is a frankly feminine confection and so very appealing.
