A hallmark is your guarantee of metal purity, independently tested by one of the four UK Assay Offices. Memento Jewellery has been registered with the Edinburgh Assay Office for over 10 years, and our gold pieces are always hallmarked.

Sterling Silver pieces are not routinely hallmarked unless a design weighs over 7.78g, so it is not uncommon for smaller items such as charms and earrings which fall below this weight to be unhallmarked. All of our heavier silver pieces over this minimum prescribed weight are assayed and
hallmarked by the Edinburgh Assay Office and will also bear our unique makers mark.
