Jewelry is already a common thing in our life, but many of us are not very familiar with the common metal materials of jewelry. Today I will share with you a little knowledge about gold and silver jewelry!
- Silver
Common silver is divided into 925 silver and pure silver.
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. Chic, beautifully crafted silverwork.
Pure silver is called pure silver with a silver content of not less than 990 per thousand. Foot silver is generally processed into bracelets, pendants, longevity lock bowls, chopsticks, cups, pots, etc. Foot silver jewelry usually has several signs, – one is S99, – one is S990, and S is the first letter of the English word SILVER (silver) , representing silver. The content is divided into 999, 990 and 925.
- Gold
Common gold jewelry can be divided into pure gold and K gold in terms of its gold content.
The gold content of pure gold jewelry is more than 99%, up to 99.99%.
Gold price is high, hardness is low, color is single, easy to wear, and the pattern is not delicate, so other metals are added to the gold material to improve the hardness. K gold refers to the alloy of gold and other metals, which is divided into 9k, 14k, 18k and 24k according to the different gold content. The higher the gold content, the darker the color and the more expensive the price.
In addition, k gold will show different colors according to the type and proportion of added metals, such as K white (white gold), K red (rose gold), K yellow (gold) and so on.
14k and 18k gold have become the preferred material for many jewelry brands because of their increased hardness due to the addition of other metals.
