Wearing silver ornaments, especially silver bracelets, is very popular. Silver bracelets are not only decorative, but also good for health. But many people buy silver jewelry and wear it very soon. There are two possibilities. One is that silver jewelry is not pure enough to oxidize, the other is that you may buy fake silver jewelry. So how to identify the authenticity of silver jewelry, the following silver concentrate will be shared with you:
1. Silver ornaments with high fineness weigh heavily and do not jump high on the platform. They have the sound of "click". Fake or low fineness are light, and they bounce very high on the platform, making a relatively clear sound.
2. Identify its color and authenticity with eyesight. High color, white, delicate, lustrous, and printed on the jewelry manufacturers, shop numbers and other signs; low color, yellowish, rough workmanship; false silver jewelry gray color, unclean.
3. After the barbecue, if it is real silver, the silver will remain unchanged; if it is false silver, or if it is inferior in color, it will turn black after the barbecue. Another method is to use nitric acid drops on the surface of silver jewelry, after wiping nitric acid, the surface of the jewelry is still silver-white, which shows that the content of silver is quite high, if the silver content is low, the jewelry will be gray-black.
4. Look at the color. Silver in a silver store will change color after a period of time. If silver in 990 turns yellow, then it becomes darker and darker, and then it turns brown, you may also change color when you buy it at home for a period of time, but it should turn black (less skin contact area). And white copper is more difficult to change color, to change is also to turn green. Silver 925 usually has an electroplating layer and is not easily discolored, but it will turn yellow after a few months.
Above is the silver concentrate to share with you to identify the authenticity of silver jewelry, I hope that silver concentrate can help you.
