22 karat gold contains 22 parts gold and 2 parts of other metals added as an alloy. Thus, 22K gold jewelry implies that 22 parts of the jewelry amount to gold and the balance 2 parts are some other metals. This kind of gold is commonly used in jewelry making. In 22K gold, of the 100 per cent, only 91.67 per cent is pure gold. The other 8.33 per cent comprises metals like silver, zinc, nickel and other alloys. It is this addition of metals that make the texture of gold harder thereby making the jewelry durable. However, you must know that although this can be used to make plain gold jewellery, 22K gold isn’t preferable for diamonds and heavily studded jewelry.
