why we in the jewellery trade add the number 925 in front of sterling silver?

A great deal of silver jewellery available today is called 925 silver। Have you ever wandered why we in the jewellery trade add the number 925 in front of sterling silver?

925 sterling silver jewelry

Sterling silver is an alloy of silver containing 92.5% pure silver and 7.5% other metals, usually copper. The minimum millesimal fineness is 925.
Fine silver (99.9% pure) is generally too soft for producing large functional objects, and in Sterling the silver is usually alloyed with copper to give strength whilst preserving the ductility of the silver and a high precious metal content.

Folklore and mass culture

Because of the mysticism surrounding silver's lunar associations, as well as the aesthetic qualities of the white, reflective metal that cause it to be associated with purity, silver in European Folklore has long been traditionally believed to be an antidote to various maladies and mythical monsters.
