(1) Check the hardness
The higher the fineness of silver jewelry, the softer the texture and the whiter and smoother the surface. Take a silver bracelet of about 60 grams as an example. If you pull it by hand, it will open and have no elasticity, and the color is about 95%. If it is a little elastic, the color is about 80% ~ 90%; If the elasticity is large, the fineness is below 70%.
(2) Look at stubble
Cut or fold silver ornaments to see the color of stubble. If the jewelry is soft, the stubble is thick and soft, slightly red, and the color is about 95%; If you bend hard by hand, the stubble is white gray or reddish, and the color is about 90%; If the hardness is large, the stubble is reddish, yellowish white or light gray, and the color is about 80%; If it is a hard bend, the stubble is reddish, yellowish, khaki and other colors, and the color is about 70%; If the stubble is red, medium and black or yellow, the color is below 60%.
(3) Silver smear test
Grind the silver ornaments on the touchstone (the same as gold inspection) and coat them with silver medicine (silver medicine is a soft mixture of silver powder and mercury), so that the color of silver medicine will be high if it is hung more, and the color will be low if it is hung less. Those without silver medicine are fakes.
(4) color identification method
Distinguish its color and authenticity with vision. High color, white, delicate, shiny, jewelry printed with manufacturers, store numbers and other signs; Low color, yellow color and rough workmanship; The fake silver jewelry is dark and not bright.
(5) Bending method
Pinch with fingers, soft and elastic, high color, easy to bend, not easy to break; The quality of the bend is hard, or barely moving, and some can't even move their fingers; The bending of silver plating or a few strokes with a hammer will crack; Fake ones can't stand bending and break easily.
(6) Throwing method
High-quality silver jewelry is relatively heavy, so it doesn't jump high when thrown on the table, and it has the sound of "poop"; Fake or poor quality is relatively light, and it bounces high when thrown on the table, making a crisp sound.
(7) Nitric acid identification method
Drop nitric acid on the file mouth of silver jewelry with a glass rod, and the dark color is brown rice, dark green or light green; Light colors are dark green or even black.
In addition, when buying silver jewelry, we should also choose the quality from the following four aspects:
(1) Look at welding. Some silver ornaments are welded, so it depends on whether the welding is clean and tidy, whether there is false welding or open welding.
(2) Look at the brightness. It requires pure electroplating color and strong brightness.
(3) Look at the veneer. Firm and upright.
(4) look at the claws. It depends on whether the claws have burrs, prick hands and scratch clothes. It is convenient to wear.
