Vintage Coro Jelly Belly Brooch Flying Duck Mallard Goose Pin ADOLF KATZ
So elegant and handsomely sized is this vintage Coro jelly belly mallard duck brooch originally designed in 1938 by Robert Geissman, and patented in 1944 by Adolf Katz.
The figural bird brooch is not sterling and instead has a metal base with gold plating and large plump clear lucite stone making up the “jelly belly”, in a layered three dimensional design.
The fanciful duck also has small faceted rhinestones set in its outstretched wings, tail feathers, and neck collar, and a Siam red stone for the eye.
*Please note that the plating at the very tip of the head is faintly lighter in color, having slightly worn over time.
The brooch measures approximately 2&1/8 inches in length, weighs 23.2 grams, and is signed “Coro” within a rectangular cartouche.
