real 925 sterling silver wholesale price jewelry How to distinguish between true and false silver?
First of all, it depends on the color. The higher the purity of the silver jewelry, the white the silver, and the surface looks uniform and shiny. If it contains lead, the jewelry will appear blue and gray; if the copper contains, the surface of the jewelry will appear rough and the color is not moist.
Secondly, weight. Silver density is slightly larger than the general common metal, aluminum, heavy silver, copper is not light and not heavy. Therefore, the weight can make a preliminary judgment on whether it is silver. If the jewelry is large and the weight is light, it can be preliminarily determined that the jewelry is other metals.
again, check hardness. The silver hardness is lower than that of copper, and it is larger than the lead and tin. It can be tested with the inconspicuous places where the jewelry is scratched by large head needles. If the needle is slippery, it is difficult to leave traces on the surface. The traces are obvious and prominent; if there are traces of the real objects but not obvious, it can be preliminarily determined as silver jewelry.
Finally, listen to the rhyme. Sterling silver jewelry is loud and non -elastic. The lower the color, the lower the sound, and the higher the sound, the higher the rhyme; if it is copper, the sound is higher and sharp, and the rhyme sounds are short and short; , No elasticity.
If you want to buy silver jewelry, it is recommended not to buy on the stalls and irregular channels. Buying silver jewelry, you still need to recognize the brand to buy it, so as not to be deceived. According to my understanding, the silver jewelry of Tiffany and the Chiliast brand is quite exquisite.
