A striking study in Art Deco geometry, this rectangular brooch pairs crisp panels of white and black onyx with a line of bright old European–cut diamonds framed in fine milgrain. Unsigned and crafted in a white precious metal, the piece embodies the 1920s taste for bold contrast and architectural symmetry. At 41.0 mm wide, it’s an elegant bar that reads beautifully on a lapel, scarf, or dress—timeless Deco glamour in pristine, wearable form.
