The pavé center is surrounded by aquamarine-glass stones on this brooch that Adolph Katz designed and Coro named Diadem. It has a gold-plated woven border with a roll-over safety-clasp and a loop that allows the piece to be worn as a necklace. An advertisement for a demi-parure in the same design but with all diamanté, reproduced in Marcia Brown’s book on Coro, reads: “Diadem Jewels by Coro … To cast a lovely light about you, an aura of excitement, a glow of elegance … first magnitude jewels at their starriest heights”. Included with the brooch is the gold-plated double snake chain with a diamanté-adorned tongue-in-groove clasp that is the same design as the brooch center. The snake chain was made for a very slender neck. Please note the chain length (14 1/4″) and check your neck size before purchasing this piece.
