Uncompromising Authenticity & UK Hallmarking

At Samuel & Co. Jewellery Limited, our commitment to the high-carat nature of our raw materials is absolute. We guarantee the purity and integrity of every bespoke piece that leaves our master ateliers.

In strict accordance with the UK Hallmarking Act 1973, every applicable precious metal asset crafted by our house is independently tested, verified, and struck with our registered Sponsor's Mark at the historic London Assay Office. This hallmark is your permanent, legal guarantee of the precious metal's exact purity (e.g., 18-carat gold or 950 platinum).

As a registered UK precious metals dealer, our statutory Assay Office Dealer's Notice detailing the anatomy of a British hallmark is displayed below for your reference.
