Services for Retailers

Submit your work to the most trusted Assay Office in the UK

We understand how important it is for you and your customers to have items processed and returned as quickly as possible. We know that the hallmarking process can appear time consuming and complicated, so we have created the most user-friendly and efficient services possible.

We were the first Assay Office in the world to launch an online booking and tracking system, which puts you in control and means you will be kept updated on the progress of your items at all times. We also offer our innovative, award-winning distribution service, which streamlines the hallmarking process, adds value, and creates more time for you to dedicate to your business.

Our expert team are always happy to provide advice on the hallmarking process, streamlining logistics, and bespoke service agreements.

Services for Retailers


As an Assay Office, our primary service is to guarantee the purity of precious metals by assaying and hallmarking articles of gold, silver, platinum and palladium in compliance with National and International regulations.

We’ve been hallmarking for more than 550 years, and our clients trust us to produce perfect hallmarks every time. Our technology and innovative approach have made us world leaders in hallmarking.

We have the equipment and systems to meet our clients’ needs and are able to apply perfect hallmarks by hand, automated press machine, or non-contact laser. We use non-destructive testing technologies, so you know your items will be returned in flawless condition.

We are committed to developing innovative new services and technologies for the emerging jewellery industry. Our award-winning distribution and third-party logistics service is designed to help our clients streamline logistics and reduce workload. The service is customisable depending on your needs as an importer or a retailer.

Full API integration allows importers to ship and track bulk or single orders through us, as we act as a true single stop between manufacturer and end customer. Goods are shipped directly to us, then hallmarked, packaged, and distributed to the end consumer – eliminating the need for extraneous stock holding processes.

Our small scale distribution service provides the same benefits for retailers who are working with smaller quantities of items.

Laser Engraving

Our laser engraving facilities apply logos, sequential numbering, and other complex engraving according to your specifications.

We can engrave in a wide range of depths and sizes. Every engraving is cleaned using a proprietry process that ensures all vaporised metals are removed.

Artwork and design quotes are available on request. For information about laser hallmarks, please visit the Hallmarking page.

Why our retailers say about us

Over the years I have dealt with the Edinburgh Assay Office, I have experienced exceptional service. The staff members are efficient, friendly and always willing to help.
A service that we request regularly is the next day turnaround, which is quick and hassle free. I would not hesitate to recommend this service to other organisations!

Sara Keegan, SWAG

I like to think we pay as much attention to detail as the team in Scotland do. The EAO enjoys being involved with customers’ business and understand their needs, frequently exceeding expectations by offering advice on processes or international requirements. It’s a great partnership and one which has grown in the same way the business has.

Ben Roberts, Managing Director, Clogau Gold
