There are many gold jewellery brands on the market today. They are not the people of gold jewellery. Consumers are always worried about the purity of gold after buying gold jewellery. So how do you judge the purity of gold jewellery? Let's take a look at the introduction below.
How to judge the purity of gold jewelry?
Rings are usually marked with 18K, 4K or 10K. K means the opening of the American language (karat), which is a system unit for describing the purity of gold. The higher the value of K, the higher the gold content of gold jewelry.
24K is pure gold.
18K gold contains 18 parts of gold and 6 parts of other metals, so gold only accounts for 75%.
14K gold contains 14 parts of gold and 10 parts of other metals, so the purity is only 58%.
12K contains 12 parts of gold, while the other 12 parts are other metals, so the purity is only 50%.
10K gold contains 10 parts of gold, the other 14 parts are other metals, so only 42% purity. 10K is the smallest karat.
