A sublime example of Tiffany & Co.’s finessed Art Deco work, this platinum and diamond ‘cocktail’ strap-bracelet — each exquisite diamond full fancy cut and polished to fit — is definitive proof that true style never dies.
An eternally elegant piece of statement jewelry; thanks to Janus Jewels, the bracelet can now also be worn as a choker, as John C. Kulukundis explains:
"I fell for the bracelet’s rare sophistication instantly. However, it also struck me how wonderful it would look if it could be worn around the neck, too. So, working with my best goldsmith, I created a bespoke platinum, diamond and velvet choker-fitting to match the bracelet perfectly."
This now extremely versatile signed jewel is sold complete with its original gilt-tooled leather Tiffany & Co. case.

Signed Jewellery refers to fine vintage jewellery that bears the distinct engraved signature of the designer or atelier that created it. Today, specific signed vintage jewels are hugely sought after due to their beauty, artistry, and historical importance. Ranging from initials and logos to makers’ marks, signatures play a crucial role in identifying and authenticating these highly collectable works. Proof of quality and provenance; sometimes, even the slight trace of a signature can dramatically increase a jewel’s worth.
Especially prized pieces include:
Cartier's 1930s gem-set panther jewels and animal novelty brooches of the 1950s-1960s.
Van Cleef & Arpels' Ludo™ bracelet: an articulated 'honeycombed' gold ribbon embellished with precious stones.
Verdura's jewelled Maltese Cross Cuffs: an early collaboration with Coco Chanel.
