WHAT IS A HALLMARK?
A Hallmark is a set of component marks which verify a products material. Precious metals are rarely used in their purest form, instead being mixed with other metals to make them more durable. Hallmarks are only applied to precious metals Platinum, Gold, Palladium and Silver.
It isn't possible to detect an article's precious metal content by sight or touch. Therefore, it is a legal requirement for items being sold as precious metal, over a certain weight, to bear a Hallmark.
Hallmarks are applied to precious metals to indicate the amount of pure metal in a product. Traditionally applied by striking with a punch, Hallmarks can now also be applied using lasers.
It is illegal to sell a precious metal product without a Hallmark and non-precious items are not permitted to have a Hallmark. Items with just 925 are not hallmarked as they are missing the other marks.
Something being sold without a Hallmark is breaking the law and there is a high chance the item may not be made from precious metal.
