How can you tell if your necklace is real 925 silver?
To identify the real 925 silver necklace we have to know some techniques.
1. Magnets have no effect on silver - just as they have no effect on gold or platinum. But if you find that the jewelry is attracted to the magnet, then it will be clear to you that it is not made of real sterling silver.
2. Rub the jewelry using a soft white cloth. If you find any black marks on the cloth, then you can be sure that it is made of real sterling silver.
3. Nitric acid has no effect on real 925 sterling silver. If the jewelry is made of real sterling silver, the part on which you drop the nitric acid will appear creamy in color, otherwise, if fake, it will appear green or lose their color.
4. Real sterling silver shouldn't smell. If it does, it is because there is too much copper in it.
5. Real sterling silver jewelry will have markings such as "Ster," "925" or "Sterling Silver" in a hidden area. If you don't see such a marking, be wary of it immediately.
6. The price that you paid for your jewelry is a good indicator as 925 silver is much more expensive than alternatives.
So by these above techniques, you can check your necklace is real or fake. Some days ago I go through "Jewelry1000.com" for top rated wholesale sterling silver jewelry, which I like most. Thanks.
