Quick Answer

One simple way to test if an item is real silver is to perform the ring test. Gently tap the silver item with something hard, such as a fingernail or another metal object. When tapped, silver produces a bell-like sound, which is higher-pitched when the percentage of silver is higher.

Another fast and easy method for testing silver is the ice test. When room-temperature silver touches ice, it causes the ice to melt more rapidly. This is because silver has the highest thermal conductivity of any metal, meaning that in a certain amount of time, more heat passes through silver than other metals.

Two other ways to test silver are checking for labels and polishing. Looking for "9.25," "925" or "Sterling" labels works best for jewelry items and dining utensils; these labels denote the purity of the silver and can typically be found on the handles of dinnerware, on the clasps of necklaces and bracelets, and inside the bands of rings. Polishing the silver with a light cloth is another good test because silver tarnishes when exposed to air; this leaves a black residue that should show up on the rag.

If none of the above tests work, the acid test, in which a purchased chemical solution is applied to a scratched area of the silver, is a reliable method for testing silver. The color the solution turns indicates the percentage of silver in the item.
