Each material has its own advantages and disadvantages, and each has its own significance, but before we choose jewelry, we should have some understanding of the jewelry material.
I will talk about common jewelry materials from three aspects: silver jewelry, gold jewelry and other materials.
Common materials for silver jewelry are 999 silver, 925 silver and silver plated.
The composition of 999 silver contains the highest silver content, with a silver content of 99.9%, also known as pure silver. Because of its high silver content, it is relatively soft and suitable for plain silver jewelry. 999 silver is particularly easy to oxidize and turn black, so it is necessary to wipe the surface lightly with a cotton cloth regularly, and do not pull it hard.
925 silver generally refers to silver products with a silver content of about 92.5%, and a purity of about 92.5% is considered pure silver. Because high-purity silver is soft and easy to be oxidized, 925 silver is added with 7.5% other metals to make it have ideal hardness and can be better shaped. 925 silver is also hypoallergenic. The oxidation and blackening of 925 silver is a normal phenomenon. It can be restored to its original state by scrubbing, and it is necessary to avoid contact with chemical substances and avoid long-term exposure to the air.
The interior of silver plating is a non-silver component, just a layer of silver is plated on the surface. The appearance of silver plating looks comparable to that of sterling silver, but the weight is much lighter, and it will fade and discolor after long-term wear, which will affect the appearance. In the process of daily wearing, it is necessary to keep the jewelry dry, avoid friction and scratches, extrusion deformation, and can not be close to chemical substances.
