Things to know about Sterling silver jewelry

What Sterling Silver Jewelry really is?

The Sterling alloy originated in continental Europe and was being used for commerce as early as the 12th century. Pure silver, known as fine silver, is very soft and can be damaged very easily so it's alloyed with copper or other metals to increase its hardness and make it more durable. 

What does 925 mean?

Sterling Silver is is 92.5% pure silver mixed with 7.5% of other metals, in our case copper. The sterling silver has then a minimum standard fineness of 925 which is the stamp that we all know.

How to properly care for Sterling Silver jewelry?

Chemically, Silver is not reactive, it doesn't react with oxygen or water at ordinary temperatures so does not form easily a silver oxide. However it is attacked by common components of atmospheric pollution as sulfur and in time it appears a black tarnish. Sterling Silver jewelry though is unlikely to tarnish when worn because it is constantly rubbing against clothing or skin. 

Anyway, tarnish can be removed from a piece of Sterling silver jewelry by dipping it in a tarnish removal liquid for a few seconds and then rinsed. It can also be removed by rubbing it with a special polish cloth.
