1, look at the color
The higher the fineness of silver, the bright white metallic luster appears on the surface, which looks like polishing and is not easy to fade, while the surface color of fake silver is dark and dull, which looks dull and stiff.
Step 2 look at the hardness
The higher the silver content, the softer the texture and the easier it is to deform, so avoid touching hard objects at ordinary times. If you bite with your teeth, it is easy to have obvious marks, while fake silver has low color, high hardness and is not easy to deform.
3. Fire
Pure silver will generally turn white after burning, but it will not turn black. If it turns black, it means it is not pure silver. Burning silver with a lighter may blacken the silver. At this time, brushing teeth with toothpaste can turn white again. As long as it can burn black, it is basically not pure silver.
4. Specific gravity
Generally speaking, true silver has high density and high specific gravity. If you weigh it carefully in your hand, there is obvious oppression, while fake silver has low silver content, low density and small specific gravity. It's not obvious to hold it in your hand.
5, marking
According to the relevant international regulations, real silver ornaments are generally marked, such as S925, AG925, S990 and AG990, while fake silver ornaments are usually not, so that they can be better distinguished.
