About our Certification

We live in an age of transparency.  Data and technology mean we rightly expect more information, where every pound spent is a vote for a better or worse world.

This is why we are proud to partner with UK-based AnchorCert Gemmological Laboratory, one of the world’s leading gemmology laboratories. Using state-of-the-art technology, they are a rigorous, neutral third party. Their skilled experts review our loose stones under the microscope before they are set, and assign each one a unique code with its own report.

AnchorCert stands fair and square on the side of the consumer, ensuring that the maximum quality and traceability standards can be met and independently guaranteed, giving end-to-end complete assurance of the authenticity of the product. Operating beyond the merely commercial sphere, AnchorCert’s experts also sit on advisory panels contributing to the review and evolution of the jewellery industry's standards.

They were established 22 years ago within the Birmingham Assay Office, itself  founded 250 years ago through an Act of Parliament.  As one of the world’s largest Assay Offices, it has been long protecting consumers of precious metals by hallmarking items of gold, silver, platinum, and palladium to guarantee the purity of the precious metal content.

By including stones such as ours, they continue that unquestionable guarantee of the very highest standards for the future.  And, like us, by being British-based they are aligned with our quest for the utmost guaranteed quality combined with trusted closest-to-home traceability. As that is what all customers rightly deserve.
