Silver to identify the real simple method of color, hardness, fire, specific gravity, mark.
1, color:
The higher the color of silver, the surface presents a bright white metallic luster, looks with a kind of moist, not easy to fall off, while the surface of the fake silver is darker in color, no luster, looks to give a person a kind of dull, hard feeling.
2, hardness:
The higher the silver content of silver, the softer its texture, but also easy to deform, so in normal times to avoid contact with hard objects, with the teeth bite, it is easy to appear obvious traces of fake silver color is low, high hardness, not easy to deform.
3, fire:

Burning silver with a lighter may be blackened silver, this time with a brush of toothpaste, to be able to re-white. As long as it is able to burn black, basically not pure silver.
4, specific gravity:
Generally speaking, the real silver density is high, than the major, will be placed in the hands of the careful weighing of the words with a clear sense of pressure, and fake silver silver content is not high, low density, specific gravity is small, will be placed in the hands of the weighing of the pressure is not obvious.
5, mark:
In accordance with international regulations, generally genuine silver jewelry will be marked with marks, such as S925, AG925, S990, AG990 words, while the fake silver jewelry is usually not, so you can better distinguish.
