The standard content of sterling silver is 92.5 p.c (.925) silver and 7.5 p.c copper. The presence of the copper increases the hardness of the alloy, making it much less likely to bend.

Sterling silver is often recognized with a marking of «925» or «ster» on the bottom or rear of a sterling silver piece.

Typically, the technique of plating is a chunk of jewelry (that is made from a certain metallic or alloy) is lined or coating with a layer of one other metallic.
