Product Details

Striking Art Deco brooch dating to the 1920s–1930s, featuring a substantial carved black onyx plaque accented with a luminous opalite glass cabochon. The sleek geometric design and architectural lines are quintessential of the Art Deco period and remain remarkably modern nearly a century later. The mounting, hinge, catch, and pin have all tested as 14K gold. The onyx has been confirmed as genuine stone, and the cabochon has been tested as glass, consistent with period opalite used in fine Art Deco jewelry. This is a beautifully executed example of hardstone Art Deco jewelry, combining luxurious materials with understated elegance.
