Design patent D146,961 issued to Adolph Katz in 1947 (application filed in 1946)
This 1940s Adolph Katz-designed gold-washed-sterling-silver brooch with deep blue-topaz and ruby glass flowers is a stunning example of the Retro Modern style and the pieces created by this company. The pavé center gathers the draped and pavé-trimmed metal. This piece from Coro Craft, the company’s high-end line, closes with a fold-over safety clasp. The same design with moonstones instead of the blue topaz was named Moonlight Sonata. It was described as “Coro’s interpretation of Beethoven’s immortal masterpiece” in a Vogue ad published in the February 1, 1946 issue.
