Pure silver is a very soft metal. While that does make it very easy to bend and move into different shapes, it also means that it is suscepitable to scratches and damage. To make the silver more durable and less prone to damage, the 100% pure silver is mixed with 7.5% of other alloys such as copper.
So, 925 Sterling Silver is 92.5% pure silver and 7.5% other alloys. 92.5% is shown as "925".
Jewellery which is 925 Sterling silver should be stamped with the mark "925". Sometimes you sill see an "S" in front the the number.
