Sterling Silver 925 VS Pure Silver 999

Pure silver, also referred to as fine silver, has actual silver content of 99.9%. Because of its high purity, fine silver is too soft to use in jewelry making and is often mixed with other metals to make it harder.

Sterling silver is an alloy created when copper is added to pure silver in order to make the resulting compound more durable and less soft.

Usually, sterling silver has a purity of 92.5%, meaning that 7.5% of the alloy is made of copper or another metal (usually nickel or zinc).



Pure Silver, Sterling Silver, and Tarnishing

Although sterling silver is more durable than pure silver, the additional metals in the alloy make sterling silver more prone to tarnishing.

This happens because the copper, nickel, zinc or other mixtures in sterling silver may react with oxygen and other elements in the air.


Sterling Silver and Plating

Often, sterling silver items are plated with a thin layer of pure silver to improve the shine of the piece.


Art Clay Silver becomes 99.9% pure silver after firing.
