Why our clients choose us again & again

The Edinburgh Assay Office worked closely with Scotgold to help design and to oversee the chain of custody for Gold from our Cononish mine. The Assay Office provided invaluable technical support, tested all gold removed from the mine and advised on the Dore production process. The Assay Office’s involvement gave everyone depending on the Scotgold project great confidence. The development and application of a Scotgold precious metal mark administered by the Assay office and linked to the chain of custody, gave each piece of jewellery that carried the mark unquestioned authenticity and enabled manufacturers and retailers to confidently and fully leverage the added value for this rarest of Scottish resources.

Diamond by Appointment and Sharman D Neill have been using the EAO’s services for a number of years. The thing that attracted us was their reputation for care and attention in the testing and hallmarking of jewellery items and we have found this to be true. In addition we commend Edinburgh Assay Office for their prompt, individual service. They have a professional and caring staff who support and endorse the strategic direction of their Assay Master. Their online submission and tracking service is simple, clear and effective to use.
