Hallmarking is the process of certifying the purity and authenticity of precious metals. It involves stamping a series of marks or symbols onto the Jewellery to indicate its metal content and the quality or standard it meets.
These marks typically include:
The Assay Office Mark: This represents the location or authority that performed the test on the metal. inOre Jewellery is registered with the Edinburgh Assay Office, which is represented by a castle symbol.
The Metal Quality Mark: A number that indicates the purity or fineness of the metal, such as "925" for sterling silver or "750" for 18ct gold and ''375'' for 9ct gold.
The Date Letter: A non-compulsory mark, a letter 'B' may be added which indicates an item was made/hallmarked in 2026. This letter changes on the 1st of Jan each year.
The Maker’s Mark: This represents the manufacturer or designer of the item. Our maker's mark at inOre Jewellery is HMC.

In the UK, hallmarking of gold jewellery (above the weight of 1g) and silver jewellery (above the weight of 7.78g) is a legal requirement. This ensures the metal content is as declared and that the item complies with specific purity standards.
