Sterling Silver (.925)

Sterling Silver is 92.5% silver and 7.5% copper. 99.9% silver is called "Fine silver." Sterling components and jewelry made in the USA are often stamped "Sterling." Goods made for international trade are often marked "925" indicating the 92.5% fineness. "Coin" silver is used in some countries and could be marked "900" or "800" depending on fineness

Other markings may be seen that are less clear. "Mexican Silver", "German Silver," "Indian Silver," "Montana Silver," or simply "silver" do not guarantee any silver content."German Silver" is another name for the alloy of Copper, Nickel and Zinc usually called Nickel Silver. Despite the name, Nickel Silver contains no silver.

For many reasons, not all silver jewelry is marked. Registering a trademark costs over $1000. The maker may not spend the money to have a legal hallmark. Small time artists and Native American silversmiths rarely trademark their work. The size or design of some pieces do not lend themselves to quality marking. Findings and components are often not quality stamped leaving the assembler the choice of attaching a mark, perhaps on a chain tab, to the finished piece.
