Hallmarking

Every piece of Ella Bonomi Jewellery is handcrafted using precious metals and hallmarked in accordance with UK hallmarking legislation where required.

A hallmark is an independent guarantee of the precious metal content of your jewellery. Applied by an official UK Assay Office, it confirms that the metal has been tested and meets the legal standards for purity.

What is a hallmark?

A UK hallmark is made up of several individual marks, which may include:

• The Sponsor's Mark – the registered maker's mark identifying Ella Bonomi Jewellery.
• The Metal and Fineness Mark – confirming the type and purity of the precious metal, such as Sterling Silver (925).
• The Assay Office Mark – identifying the Assay Office that independently tested and hallmarked the piece.

Which pieces are hallmarked?

Under UK law, sterling silver weighing over 7.78 grams and gold above the legal weight thresholds must be hallmarked before they can be sold.

Pieces below these weight limits are not legally required to be hallmarked, although they are still made from the precious metals stated in their product descriptions.

Why does hallmarking matter?

Hallmarking provides reassurance that your jewellery has been independently tested and verified. It is one of the oldest forms of consumer protection in the UK and reflects a commitment to quality, craftsmanship and authenticity.
