Founded in 1997, The Diamond Box is a family-run jeweller now in its third generation, built on a passion for luxury watches and fine jewellery.

Starting from a small shop in Harlesden, the business grew through word of mouth, driven by strong customer service, competitive pricing, and a carefully curated selection of Rolex, Cartier, and fine jewellery.

Now based in Finchley Central, The Diamond Box offers a wide range of luxury watches and jewellery, alongside expert repairs and servicing, both in-store and online.

As the business has grown, its focus has remained the same: great service, quality pieces, and a genuine commitment to its customers.
