What does it 925 sterling silver mean?

Pure silver has 99.9% of silver, and a small content composed of other metals such as copper. Sterling Silver consists of 92.5% silver, and the remaining part consists of mostly copper. This is the reason why Sterling Silver is popularly referred to as 925 Sterling Silver or just 925 Silver.

Pure silver is very soft and malleable and needs to be combined with other metals to make it harder so the jewelry made with it will be durable, so hardness has to be introduced, by adding other metals such as copper. 

Ways to distinguish 925 sterling silver 

1. Rub the jewelry item with a piece of white fabric.

If dark marks appear on the on the fabric where you've rubbed it, then you know it's real sterling silver. This is because the copper that is added to pure silver to make 925 is oxidizing (tarnishing) because it reacts to the air. The real stuff tends tarnishes, fake silver or silver plated metal alloy jewelry fades in time revealing an obvious copper later.

2. The Nitric Acid Test. 

Professionals use drops of nitric acid are added to counterfeit non-silver gems, they cause them to lose their shading. Continuously ask a goldsmith before purchasing 925 sterling silver from him on the off chance that you can lead the nitric basic analysis on it.

Nitric corrosive has no impact on genuine s925 sterling silver, so if the goldsmith is moving you a real item, he won't have any complaint to that. Be that as it may, make certain to wear gloves and ensure your eyes with goggles while doing the nitric basic analysis.

In the event that the adornments are made of genuine sterling silver, the part on which you drop the nitric corrosive will seem velvety in shading, generally, if counterfeit, it will seem green.

3. The Smell Test.

Genuine sterling silver shouldn't smell. In the event that it does, it is on the grounds that there is excessively copper in it.

4. The Magnet Test. This is a basic test. Magnets have no impact on silver – similarly as they have no impact on gold or platinum. However, on the off chance that you find that the adornments are pulled in to the magnet, it will be obvious to you that it isn't made of genuine sterling silver.

5. Genuine sterling silver adornments will have markings, for example, "Ster," "925" or "Sterling Silver" in a shrouded territory. On the off chance that you don't see such a checking, be careful about it quickly.
