Hallmarking Birmingham Assay

Jewellery is an investment.  To protect higher value items, supplied within the UK, we have a long history of items over certain weights need to be assayed to assess the metal purity and hallmarked to certify they are the purity, have been tested and to confirm the brand with the brand mark.

Where required or considered desirable, Ojewellery exclusive designs are now hallmarked at the Birmingham Assay Office  - marked with the Anchor Assay Office Mark and Ojewellery's makers mark the letters OJ within a hexagon.
