Hallmarking
In an age where consumer protection and rights are a key concern for most present-day manufacturers it is fascinating to note that the hallmark is, in fact, one of the oldest forms of consumer protection that exists. The history of the hallmark dates back as far as 1300.
Analytical Services
We offer a range of additional analytical services from metal and mineral analysis, to mercury screening and environmental testing. Sheffield Assay Office was the first UK Assay Office to be awarded UKAS accreditation and is proud to have retained that accreditation for 32 years.
Diamond Verification
Services (DVS)
As the number of lab-grown diamonds in the market continues to soar, we recognised an urgent need for retailers, and consumers alike, to have access to a fully independent, specialist service that can accurately identify the presence of natural or lab-grown/synthetic diamonds.
