Home/ Jewellery Hallmarking
Hallmarking Is Your Guarantee
At ONE+ONLY, we believe it is important for our jewellery to remain in qualified hands. As such, we have all our jewellery hallmarked at the renowned and respected Edinburgh Assay Office (EAO), guaranteeing that our customers are getting nothing but the very best.
Hallmarks & What To Look For
Hallmarks are a series of marks stamped on jewellery or other precious metal items, that can only be applied by an independent Government-authorised Assay Office.
The Hallmark stamped on your ONE+ONLY jewellery will be in an inconspicuous location, and will consist of at least three compulsory parts:
1The Sponsor's Mark
This unique mark identifies the maker or sponsor who has sent the items to be hallmarked.
2The Fineness Mark:
Denotes the fineness of the metal. The purity of the precious metal content is recorded in parts per 1000. For example, 14 carat gold jewellery must contain 585 parts per 1000 of pure gold. Gold jewellery meeting this standard will be marked with 585 to denote 14 carat.
3The Assay Office Mark:
Indicates which UK Assay Office tested and marked the item.
