Metal Fineness
A compulsory hallmark that shows the exact purity of the precious metal in parts per thousand. For example, sterling silver is stamped as 925, 9ct gold as 375, and platinum as 950. This ensures transparency and trust, giving buyers confidence in the metal quality of luxury jewellery and golf markers.
Date Letter Mark
A hallmark that shows the year your piece was tested and hallmarked. Each year is represented by a specific letter in a distinctive font and shield shape. This detail makes hallmarked silver, gold, and platinum pieces not only traceable but also historically significant, adding lasting value to luxury items.
Traditional Fineness Mark
A classic symbol used on precious metals such as sterling silver, gold, and platinum. This mark represents the traditional standard of purity (for example, the lion passant for silver) and adds heritage value to your hallmarked piece.
Assay Office Mark
A compulsory stamp that identifies which official UK Assay Office has tested and verified the metal’s purity. Each office, such as London, Birmingham, Sheffield, or Edinburgh, has its own unique symbol. This hallmark guarantees your item has been independently checked and certified to legal standards.
