Gold Hallmarks Explained
A beginner’s guide to reading purity marks and understanding what hallmarks can tell you.
A hallmark is a mark used to communicate information about a precious-metal item. Depending on the jurisdiction, it may indicate purity, manufacturer, assay office or other details.
Common purity marks
Marks such as 750, 585 or 916 often indicate fineness, while marks such as 18K or 14K use the karat system. A mark should be interpreted in the context of the item and local standards.
Hallmarks are useful, not infallible
Counterfeit items can carry false marks. A hallmark is therefore one piece of evidence rather than absolute proof of authenticity.
When to get help
For expensive or unfamiliar items, a qualified jeweler, appraiser or precious-metals professional can help interpret marks and test the metal.
Key takeaway
The best gold decisions usually come from understanding the product, the price components, the risks, the seller or custodian, and the purpose the gold serves in your plan. Compare multiple sources and verify important details independently.
