Coro Milk glass ruffled ribbon/flower brooch patent 1954 A Katz

For your consideration, a rare vintage 50s ruffled ribbon brooch signed CORO featuring white milk glass beads and clear baguette rhinestones forming a flower. Original ADOLPH KATZ design dated back 1954. Beautiful and rare brooch – I've never seen another one like it – in the shape of a five-petal corolla in gold tone metal with white enamel. Each petal is decorated with white acrylic material, probably lucite, five beads of three different sizes. At the center of the corolla, clear baguette rhinestones. This delightful model was patented in 1954 by ADOLPH KATZ, the chief production manager who, starting in the 1920s and for nearly four decades, created the style for which CORO is still famous today. (In the last image, the original patent signed by Adolph Katz). This pin is simple, but very complex and rich in elements. The brooch has a generous 4.5 cm diameter (1 inch and 12/16) and weighs 23 grams. The brooch is in pre-owned vintage condition, as seen in the photos with some wear to plating, the metal is intact and elements in lucite and rhinestones are all present and well preserved. The plating shows some wear/aging signs, not really noticeable when worn, the clasp holds securely.
