Welcome to our Hallmarking Guide! Let's take a journey through the world of hallmarks found on gold jewellery and learn how to decode them.
What's a Hallmark?
A Hallmark is a tiny mark placed on your jewellery. It's like a secret code that tells you about the metal's purity, the jewellery's origin, and who gave it the stamp of approval. It acts as a protection for buyers as it ensures the jewellery is genuine.
The 3 Must-Know Hallmarks:
Sponsor/Makers Mark: Everyone who makes or sells precious metal jewellery has their own unique mark registered with the Assay Office. It's like their signature on the piece.
Standard Mark: This mark shows how pure the metal is. Think of it as the carat indicator, assuring you that your jewellery is of the highest quality.
At Sacet, we work with these recycled precious metals and their corresponding hallmarking numbers:
925: Sterling Silver
375: 9k Gold
750: 18k Gold
Assay Office Mark: Each piece of jewelry gets tested and stamped at an Assay Office. The UK has 4 of these offices—Birmingham, Edinburgh, London, and Sheffield. Each one has its own special symbol: anchor, castle, leopard, and Tudor rose. These symbols help trace your jewellery's journey.
