Gold for jewelry is usually mixed with other metals. This is because pure gold (100%) is very soft and difficult to set up. Metals commonly used for mixed materials are nickel, copper, silver, zinc, rhodium and other. Jewelry with a gold content of 80% stated that the gold content in the jewelry is 80%, while 20% were in the form of a mixture of metal instead of gold.

For indeed the benchmark price is the content of the gold content in jewelry. The higher the gold content in jewelry, the higher the price. Once again do not be fooled by the carat.
