This independent British jeweler specializes in gold and silver cufflinks for true connoisseurs. While they carry a huge range, including enameled and jeweled styles, Longmire is known for its unique designs that will identify the wearer as a man of power and strong personality. There are three separate shops in London with the one on New Bond Street featuring the haute couture line and the original shop in Bury Street displaying more traditional pairs. The custom department will memoralize your dog, family crest, company logo, initials or plane’s tail number in enamel or engraved cufflinks. Some recent designs: a small silver handgun, a pavé diamond bull’s head and a white gold skull with a top hat and sapphire eyes.

In the heart of Chelsea, jeweler Theo Fennell works with a team of craftsmen to create his iconic pieces of silver and jewelry in the same building that houses his flagship store.

After all, Cartier and Asprey are unlikely to introduce diamond encrusted skulls.
