A Hallmark guarantees the quality of the metal you are buying by showing that the item has been independently tested and is one of the legally allowed qualities for a jeweller to sell to you in the UK. Most items should be hallmarked although some items below a certain weight or that are very delicate may not need to be hallmarked so if we sell an item without a Hallmark, that is because it does not have to have one.
