Jacques took charge of the London operation of Cartier in 1909 and eventually moved to the current location at 175 New Bond Street.
Cartier was very lucky in getting the recommendation of Princess Mathilde, the young cousin of Napoleon III, and this contributed to the boosting business.

Jacques then proceeded to India, carrying magnificent jewellery of local maharajahs back to the London studio to redesign and modify for their own use.
The uniqueness of the pearls and stones created a sense of each piece of jewellery being special, which helped with the success of their business.
