Hallmarking

Hallmarks are tiny marks stamped or lasered on a piece of precious metal jewellery and can be usually found on the inside of the ring, or back of the piece like brooch or pendant.

All our bespoke pieces or any pieces that we manufacture will have hallmarks; we are required by law to include them in any items we sell as gold, platinum, palladium or silver. There are exceptions when we are not required to hallmark pieces of jewellery - for example the time the particular piece was manufactured of if it falls under the weight requirement for hallmarking.

All hallmarks must contain several symbols each informing us about a characteristic of the piece:

Sponsor's mark - also known as Maker's Mark  - a symbol of the registered maker usually in the form of letter/initials
