The Tiffany name is synonymous with luxury, and this onyx and diamond “bow” brooch perfectly demonstrates why this firm is so beloved. Crafted in a sophisticated, streamlined Art Deco design, this brooch sparkles with 1.95 total carats of diamonds, including the stunning .65-carat round brilliant-cut gem at its center. This versatile piece also converts into a pendant able to be worn on its platinum chain.
