WHAT IS THE DIFFERENCE BETWEEN PURE SILVER AND 925 STERLING SILVER?
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.
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.
