  • The Challenge

    A global jewellery retailer expanding into the UK needed a trusted partner to help them navigate UK hallmarking law, establish credibility with new customers, and ensure their products met regulatory standards. Entering a mature and highly competitive market, the retailer also wanted to reassure customers about the authenticity of diamonds and gemstones, particularly being transparent on communicating natural or laboratory grown diamonds to their customers. Their priorities were to:

    1 - Gain confidence in meeting UK legal requirements for hallmarking and precious metal compliance.

    2 - Build trust and transparency with UK consumers through independent diamond verification.

    3 - Differentiate their brand by offering value-added services beyond traditional retail.

    4 - Educate both staff and customers on the differences between natural and lab-grown diamonds.

  • Our Approach

    Birmingham Assay Office worked with the retailer to design a bespoke support package for their UK launch:

    1 - Hallmarking & Legal Compliance – Full guidance on hallmarking law and support with registering a sponsor’s mark, ensuring legal compliance from the outset.

    2 - Gem Lab Services – Expert identification and analysis of diamonds, including clear distinction between natural and laboratory grown diamonds. Certificates provided to support customer confidence at point of sale.

    3 - Training & Education – Bespoke training for retail employees on hallmarking, diamond verification, and how to confidently explain the differences between natural and lab-grown stones to customers.

  • The Results

    1 - The retailer launched with a fully compliant product range, backed by Birmingham Assay Office hallmarking.

    2 - Customer trust increased thanks to diamond reports verifying natural and lab-grown diamonds.

    3 - Employees gained confidence in explaining hallmarks and gemstone reports, strengthening customer relationships.

    4 - The retailer quickly established itself as a trusted new entrant in the competitive UK luxury market.

“As a new entrant into the UK market, Birmingham Assay Office gave us the expertise and credibility we needed. Their hallmarking and gem lab services, especially in distinguishing natural from lab-grown diamonds, gave our customers complete reassurance. Birmingham Assay Office were also able to support us with our supply chain to ensure our product flowed in the most efficient way to deliver in store on time, every time.“
