Antique Art Deco Onyx and Marcasite Cocktail Ring, c. 1920

A ring that speaks in hushed elegance—the inky depths of polished onyx, framed by a constellation of glittering marcasites. This striking Art Deco cocktail ring is the essence of 1920s glamour, where contrast was key, and drama was everything. The smooth, mirror-like black onyx draws the eye, an understated yet powerful centerpiece, while a halo of hand-set marcasites flickers like city lights against a midnight sky.

Crafted in silver and hallmarked as STERLING, this ring dates to the Art Deco era, around 1920. The substantial onyx measures 22 x 15 x 2.2 mm, surrounded by 32 marcasites that catch and reflect the light with every movement. The overall dimensions of the ring are 28 x 21 x 5 mm, with a 3 mm band for a comfortable fit. Weighing 9.1 grams, it carries a satisfying presence on the finger without being overpowering. An additional partial hallmark "A C i", further adds to its history and authenticity.

Perfect for those who appreciate the bold elegance of Art Deco design, this ring is a conversation starter, a statement piece, and an heirloom all in one. Whether paired with evening attire or worn as a striking everyday accessory, it is a testament to a bygone era of style, sophistication, and confidence.
