WHAT IS 925 STERLING SILVER?
925 Sterling Silver is an alloy of silver containing 92.5% pure silver and 7.5% other metals, usually copper. Fine silver (99.9% pure) is generally too soft for producing large functional objects, and in Sterling Silver, the silver is usually alloyed with copper to give strength whilst preserving the malleability of the silver and a high precious metal content – ideal for making silver jewellery
Other metals can replace the copper, usually with the intent to improve various properties of the basic sterling alloy such as reducing casting porosity, eliminating firescale (a red or purple stain), and increasing resistance to tarnish. These replacement metals include germanium, zinc, and platinum, as well as a variety of other additives including silicon and boron.
