The way to identify the Authenticity

Silver is one of precious metals in the word. Sterling silver is much cheaper than expensive metals such as gold, and yet, fake sterling silver jewelry is sold in the market. What is very important is not to be duped into buying fake sterling silver jewelry. There are many ways to test the sterling silver jewelry. Do you know how to identify the authenticity?


1). Look for markings, such as: 999, S925, or 925. Sterling silver is 92.5% pure silver that’s mixed with another metal alloy, usually copper. So the sterling silver jewelry is labeled with S925, 925. A stamp that says “999”is pure silver jewelry.

2). Run magnet over the silver jewelry you want to test. This method is simple. Sterling silver isn’t magnetic, so should not see your silver jewelry move. Magnet also has no effect on gold and platinum.

3). Burn your silver jewelry. After high temperature, the silver will appear original silver color. It is also a way to test silver jewelry.

4). Rub your silver jewelry with a soft white cloth. If you find any back stain on the cloth, then you can be sure it is real silver jewelry. This is because real silver jewelry will oxidize in the air when exposure to the air.

5). You can test the silver jewelry by drops of nitric acid. Nitric acid has no effect on real sterling silver, if the jewelry is made of real sterling silver, the real one will appear creamy in color and fake silver will lose their color. But be sure to wear gloves and protect your eyes with goggles while doing the nitric acid test.
