Design patent D148,246 issued to Adolph Katz in 1947
This Duette, Coro’s name for their double-clip brooch, is a pair of leaves with emerald-cut and round diamanté set in rhodium-plated base metal. Designed by Adolph Katz, this piece can be worn as a brooch or as separate fur clips. This substantial double-clip brooch was advertised in the December 1, 1947 issue of Vogue and the April 1948 issue of Mayfair. The ad in the last photo shows an example of how to wear the clips. You can see the utility patent for the brooch mechanism here, beneath Coro’s name.
A large faceted pear-shaped emerald rhinestone is the focal point in this glamorous 1950s gold snake chain necklace designed by Adolph Katz for Corocraft, Coro's high-end line. Emerald rhinestone baguettes embellish the gold-plated centerpiece. The chain closes with an emerald-topped folder-over clasp.
This 1940s brooch features amethyst, ruby and peridot glass stone calla lilies tied in a bow and accented with fuchsia and blue glass stones and diamanté. The setting of this Retro Modern piece has a rose-gold wash over sterling silver, with a roll-over safety clasp. Although the drawing in the design patent shows this brooch with the flowers facing down, I prefer them facing up because they look as though they're reaching for the sky! You can see this brooch in this orientation in the third photo. This gorgeous Adolph Katz design from Corocraft, Coro's high-end line, was also made with all citrine glass stone – scroll down to see that version.

This piece was advertised along with the complete Platina line in a 1940s fashion magazine.
