The shape of the Colosseum was fashioned into a dynamite ring that embodies everything Roman about Bulgari. More than two million have sold since it launched in 1999, and it has spawned myriad spin-off designs.

When Coco Chanel first layered strings of fake pearls over her restrained new look, she singlehandedly invented costume jewellery. The styles have changed and developed since the 1920s, but strings punctuated with the distinctive diamante CC emblem remain core products.

The amorphous shape of Peretti’s cuff for Halston and Tiffany & Co. looks like a freeze-frame of pooling mercury. It is the essence of the 1970s Liza/Studio 54 era of New York, when Halston was the svengali of Manhattan fashion. Peretti took inspiration from skeletons in the crypt of the Capuchin church in Rome, but made it glam, silver and disco.

It looks like it was custom made for a Helmut Newton shoot, and sits in that perennial sweet spot between kink and luxe, but as the name suggests, the Hermès Collier de Chien started out as an actual dog collar in the 1920s. It was worked into a belt design a few years later, then as a leather and metal studded bracelet in the late 1940s.

As Mid-Century Modern as anything by Charles and Ray Eames, Tiffany & Co. has played on chunky links ever since the Tire Track Link bracelet of the 1940s. Vintage pieces sell for around £10k. The industrial aesthetic has filtered down today to the 1837 and Tiffany & Co. City HardWear collections.
