Hallmarked for Trust

Our Commitment to UK Hallmarking Standards

At John McKay Jewellers, trust and transparency are at the heart of everything we do. As a long-established, award-winning jeweller based in Paisley, we proudly adhere to all UK hallmarking laws—ensuring that every item of Gold, Silver, Platinum, or Palladium jewellery we offer is accurately tested and hallmarked in accordance with legal standards.

We work with recognised UK Assay Offices—London, Birmingham, Sheffield, and Edinburgh—to certify the precious metal content of our pieces. A hallmark not only confirms authenticity but also offers peace of mind to our clients.

We encourage all customers—whether purchasing from us or elsewhere—to look for a hallmark when buying precious metal jewellery. It's your guarantee of quality and protection.
