Condition Notes: This bold arrow brooch channels the sleek drama of Art Deco design radiating fan-like segments of yellow gold and diamonds, anchored by a sharp onyx and diamond-set stem. The contrast of tone and texture, gold, black, and brilliant white, gives it both structure and movement. A stylized spark. Marked with unknown maker's mark, 18k. White metal tests as platinum. Completed by a pinstem and catch. There is visible glue residue at the junction where the black onyx meets the platinum on the side of the brooch.
