Cartier's New Bond Street boutique, which opened in 1909, offers no-expense-spared jewellery and watches, as well as a selection of luxury leather goods. Cartier's commitment to quality and tradition has sealed its reputation as one of the most sought-after jewellers in the world: its signature gold cufflinks and engagement rings emphasise conservative refinement. The oak-panelled flagship is the perfect setting to peruse the engagement ring selection.
