Ask If It's Hallmarked

We are please to advise that all items on this website over the required hallmarking weight

are marked at British Assay Offices.





Our Commitment to Hallmarking

When it comes to manufacturing jewellery and silverware, precious metals (silver, palladium, gold and platinum) are rarely used in their purest form. Instead they are usually alloyed with lesser metals to achieve a desired strength, durability, and colour.
It is not possible to detect the precious metal content of an item by sight or by touch. It is, therefore, a legal requirement to have items consisting of silver, palladium, gold or platinum independently tested and then hallmarked before they can be described as such. Items must bear a hallmark at point of sale, subject to the following weight exemptions:

Silver: mandatory for items above 7.78 grams;

Gold: mandatory for items above 1 gram;

Palladium: mandatory for items above 1 gram;

Platinum: mandatory for items above 0.5 grams.

Note that all items below the mandatory hallmarking weights will not bear a full UK hallmark.

Ophir Jewellery is registered with the Assay Assured scheme which is run by the Edinburgh Assay Office, ensuring our precious metal jewellery is compliant with the UK’s hallmarking regulations. All stock is subject to an internal confirmation process to ensure it meets the UK’s hallmarking regulations before it is dispatched to our customers.
We are an Assay Assured Jewellery Retailer. Assay Assured status is only given to retailers who have been independently audited and verified by Assay Assured which is run and overseen by the Edinburgh Assay Office, and ensures that all precious metal jewellery (except items exempt by weight) are independently tested and hallmarked.
