As the folk jewelry that leads the trend of the times, silver jewelry is increasingly sought after and loved by people. Due to the low cost of silver jewelry, many unscrupulous merchants took the opportunity to fish in troubled waters and made up their minds on the processing of silver jewelry. Here, China Jewelry Merchants Network should remind everyone that buying silver jewelry must look for the brand, to the regular business to buy, will not be deceived.
Ok, let's go back to the key point we want to talk about today. In the current silver jewelry market, how should we judge the quality of silver jewelry?
Long silver silver
First of all, we must check the imprint, according to the national standard "GB1187-8P", the silver content is not less than 925% called 925 silver, silver 925 imprint; silver containing not less than 990 ‰ is called full silver, full silver mark Or hit the silver 990 mark.
Secondly, the higher the purity, the whiter the silver, the finer the surface, the evener and brighter, and the touch. If it contains lead, the surface is blue-gray; if it is copper-containing, the surface is rough and dry. Although the oxidized silver has a "black rust" on the surface, its color is black and bright, and lead, tin and white copper have no luster.
Since the density of silver is slightly larger than that of common metals, it is generally said: "Aluminum is light, silver is heavy, and copper is not light or heavy." Therefore, the weight can be judged whether it is silver or not. In addition, the hardness of silver is lower than that of copper, and it is larger than that of lead and tin. Therefore, it can be tested with a small pin to draw the surface of the object. If there is trace and it is not obvious, it can be initially judged as silver jewelry.

For the common counterfeit silver on the market, it is generally made of white copper, lead, tin, aluminum, etc. Its characteristics are: the appearance of white copper is grayish white, the mouth is brick gray, green rust; the lead is grayish blue. It is soft and can be traced with nails; tin is silvery white and soft; aluminum is white and gray, soft in texture and light in weight.
In addition, there is another way to look at the mouthwash, cut the silver jewelry horizontally in half, look at the color of the mouthwash, the mouth is snowy white and cotton, the color is about 98%; the bend is harder, the mouth is white with gray or slightly Red, the color is about 90%; the bending is hard, the mouth is reddish, yellowish, earthy yellow, etc., the color is about 70%; the mouth is black with black, the yellow is black, and the color is about 60%.
In the old days, the color of silver used as a silverware was more than 80%. Folk craftsmen also use silver and copper and other metal alloys to make silver ornaments, which can improve the physical properties of silver ornaments, and the color has also changed to achieve better results.
Therefore, the choice of old silver ornaments is not necessarily the choice of more than 90% of the color, mainly to choose the work, choose the style, choose the most suitable for their own eyes.
