Breathtaking brooch from Hattie Carnegie features black on black coloring. The opaque navettes encircle the center glass cabochon which is in an enameled setting that resembles petals. The setting is known as "japanned" meaning it is in black also. This is a very large (3 inches in diameter) brooch and also very dimensional as the center sits up about 3/4 inch high. Signed on an oval cartouche as shown. Condition is fine with no issues. There is a hook on the back, not really large enough to be called a bale, but it would allow you to wear this on a chain if you wanted to. I think it would look fantastic on a crystal clear rhinestone chain.
Great find from a fantastic designer, who was known for her clothing as much as her jewelry.
