What Is Sterling Silver?
Most of us have come across the term sterling silver. This is sometimes called 925 silver or 92.5% silver too. So what exactly does sterling silver mean? Here is the explanation for sterling silver jewelry. When jewelry is being made, the metal used needs to have sufficient hardness. If this is not the case, a soft metal cannot withstand the various production stages of jewelry production. Silver in it's purest form is considered to be too soft for jewelry applications. It is therefore necessary to increase the hardness of pure silver before it can be used in jewelry manufacturing.
An alloy consisting of a few metals is added to pure silver to increase it's hardness. It is obvious that the addition of any alloy reduces the purity of the silver. The proportion of alloy and silver in the final metal are important. If the silver content in the mixed metal is not less than 92.5%, the metal is referred to as sterling silver or 925 silver. Sterling silver jewelry should therefore contain a silver purity of 92.5%. It is now obvious that the term 925 silver refers to the purity of the silver in the jewelry.
While the sterling silver standard has been in place for a few decades now, a few jewelers continue to produce silver jewelry with silver purity that is as low as 50%. We have come across certain silver jewelry produced in India that had a silver purity of just 50%. You should know that such silver cannot be termed as sterling silver.
