Led by architect Laura Gonzalez, each area is lavished with handcrafted, decorative walls, complemented by glass and bronze furnishings. Glossy wood and rounded corners add retro flavour, bolstered by opulent, geometric chandeliers.

This space houses the full Cartier product portfolio, including a high jewellery collection in festive red, white and gold. Highlights include a pair of ritzy ruby earrings and a platinum and diamond necklace made up of creamy pearls and yellow diamonds, which dramatically drip down the décolletage. Further delights include the Clé de Cartier Serti Vibrant timepiece, bedecked with rubies and brilliant-cut diamonds and a Rotonde de Cartier watch with a Harrods-green dial.

Both Cartier and Harrods date back to the mid-19th century and are synonymous with timeless luxury and impeccable design. Each one honours an esteemed heritage whilst purveying cutting-edge, contemporary products – all of which look supremely pretty under the Christmas tree too.
