International Gold Hallmarks
Gold hallmarks are symbols or marks that are stamped on gold items to indicate their purity and authenticity. They are used to ensure that consumers are getting what they pay for and to protect them from fraud.
There are many different gold hallmarking systems in use around the world, but the most common is the carat system. The carat system measures the purity of gold on a scale of 24. Pure gold is 24 carats, and 18-carat gold is 75% pure gold.
Other common gold hallmarking systems include the fineness system and the millesimal system. The fineness system measures the purity of gold in parts per thousand, so 18-carat gold is 750 fine. The millesimal system measures the purity of gold in grams per kilogram, so 18-carat gold is 750 grams of gold per kilogram.
Gold hallmarks are typically stamped on the inside of gold items, but they can also be found on the outside. The hallmark will usually include the following information:
* The carat or purity of the gold
* The name or logo of the assay office or other body that certified the gold
* A date mark to indicate when the gold was assayed
* A sponsor’s mark to identify the manufacturer or seller of the gold item
Gold hallmarks are an important way to protect consumers from fraud and to ensure that they are getting what they pay for. When you buy gold jewelry or other gold items, always look for a hallmark to verify its authenticity.
