What is a jewellery hallmark?
Since it’s not possible to tell what rings are made of just by looking at them or feeling them, it’s a legal requirement to hallmark pieces of jewellery and other items that contain precious metals. The metal is analysed to determine its metal type and purity and is then marked with a series of symbols, known as its hallmark.

How is hallmarking done?
Precious metals are rarely used in their purest form and are typically alloyed with other metals for strength, colour and durability. The hallmarking process is completed in a few technical steps.

Every Taylor & Hart item is hallmarked at The Goldsmiths’ Company Assay Office in London with the full, traditional UK hallmark. This includes three compulsory punch marks and two additional marks to prove that the piece has been independently tested, guaranteeing that it conforms to all legal standards of metal purity.
