Sterling silver is an alloy of silver containing 92.5% of silver and 7.5% of other metals, usually copper.
Often, sterling silver and silver are described as the same thing, but in reality, sterling silver is only an alloy of silver. Silver, which is usually called fine silver, consists of 99.9% pure silver, is relatively soft, so silver is usually alloyed with copper to increase its hardness and strength.
Sterling silver is prone to tarnishing, and metals other than copper can be used in alloys to reduce tarnishing, as well as casting porosity and fire scale.
Sterling silver is the brightest of all the precious metals. Many people prefer to wear sterling silver jewellery more than any other metal because they love the bright, shiny look of jewellery produced in sterling silver. Over the years, the popularity and value of Sterling silver has risen.
Mostly sterling silver jewellery comes with 925 stamping.
