Diamond Brothers, luxury watches and jewellery in London

Diamond Brothers is a London-based establishment dedicated to buying and selling luxury watches and creating bespoke jewellery. Its watch catalogue includes pieces from Rolex, Patek Philippe, Audemars Piguet, Richard Mille and Cartier, with specific models such as the Rolex Datejust, Daytona, Day-Date, GMT Master II, Submariner, Air King, Oyster Perpetual, Yachtmaster, Lady's Datejust, Sky-Dweller, Pearl Master, Land-Dweller, Explorer and Milgauss; the Patek Philippe Aquanaut, Nautilus, Ladies Nautilus and Calatrava; the Audemars Piguet Royal Oak, Royal Oak Offshore and Lady Royal Oak; as well as references from Richard Mille and Cartier.

Watches: buy, sell and exchange

The firm presents itself as a watch specialist and offers several ways to trade: purchasing pieces from the catalogue, selling watches on behalf of individuals and a service to source a specific watch. The catalogue usually features watches with box and papers, and among the published examples are several Rolex Datejust 69178 with different dials — white with Roman numerals, champagne, black with diamonds, custom mother-of-pearl, blue vignette with custom bezel and olive with diamonds — with prices at the time of analysis ranging from £9,850 to £11,250.

Bespoke jewellery and engagement rings

The jewellery section revolves around bespoke creation. Clients can start from a setting, a natural diamond, a lab-grown diamond, a coloured diamond or a gemstone, and choose the stone shape from round, oval, emerald, pear, radiant, cushion, princess, marquise, heart and asscher. The offering includes engagement rings — with eternity, halo, three-stone, cluster and gemstone variants —, cocktail rings, earrings (stud, hoop and drop), necklaces and bracelets, as well as named collections such as Toi Et Moi, Starlight Pearl, Kaleida, Mayfair, Gaia, Confetti, Olympia, Tea and Primrose. It also has ready-to-wear rings with next-day delivery.

After-sales services and advice

Alongside sales, Diamond Brothers offers watch servicing and repair, watch polishing and personalised assistance to answer queries, with online chat and messaging channels. The company states that it works with conflict-free diamonds and that the stones used come with certificates proving this. It also offers the possibility of arranging an appointment to view the watches via video call or in person.
