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).
There is also the so-called coin silver, which is an alloy of lower purity: It usually contains 90% or less silver.
