The purity of gold jewelry

Many people know that the purity of gold jewelry is not the same. People will divide gold into many types according to the ratio of pure gold contained inside. Gold purity is classified as pure gold. The so-called pure gold does not refer to this gold. The proportion of pure gold is 100%, but it is said to be close to 100%. The amount of pure gold on the market that is more than 99% is also called "full gold." Gold itself is too soft and tough. Accessories made of pure gold, hinges and connecting positions will be more easily deformed and dismantled. In general, alloys will be added to increase the strength of gold. Therefore, the so-called gold jewellery actually refers to the gold component used in the jewellery itself and does not include the gold component of the weld or hinge.
