What is Gold Purity? Gold purity refers to the amount of pure gold content in an item. The purest form of gold is 24 carat, which means it contains 99.9% pure gold. However, pure gold is too soft to be used in most jewellery or other everyday items, so it's typically alloyed with other metals to make it stronger and more durable. The carat ...

As mentioned earlier, millesimal fineness figures could also denote gold purity. For example, a gold alloy containing 58.3 percent pure gold could also be referred to as 585 instead of 14k. A gold article that is 91.6 percent pure gold could be referred to as 916 gold. Several European nations use decimal hallmark signs instead of gold karats.

Therefore, gold jewelry is often made of more than just pure gold. There is a slight impurity or a significant presence of other metals. Other naturally occurring metals, usually copper, silver, zinc, etc., are added to boost gold's durability and maintain its form.
