Our Commitment to Hallmarking

When it comes to manufacturing jewelry 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 color.

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.

Molly Brown London is registered with the Edinburgh Assay Office, ensuring our precious metal jewelry 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.

Molly Brown London operates a process where all items are hallmarked regardless of weight.

We are very proud to be an Assay Assured Jewelry 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 jewelry (except items exempt by weight) are independently tested and hallmarked. This is a testament to the quality of our jewelry and the care and attention we take to ensuring that our children's jewelry is simply, the best.

All Molly Brown London jewelry carries the British hallmark, a guarantee of quality that has existed for over 700 years.
