does sterling silver turn color
Trending Now. Answers. Best Answer: Sterling silver is 92.5% pure silver the other 7.5% is an alloy including copper. Copper can oxidise when in contact with your skin or with the air. Therefore the alloy component can discolour and/or tarnish, turning your sterling silver brownish (tarnish) or grey-black (oxidised). You can clean it with a silver cleaning cloth from a jeweler's or even from the supermarket. (Do not use chemical cleaners if the silver jewelry has gemstones or pearls in it.)
