About the precious metal Silver - silver jewelry that has not been coated with any kind of coating has a natural appearance and color.

Silver is a universal metal that almost never causes allergic reactions. Among the disadvantages of silver jewelry without a coating is their darkening, which occurs over time, which can be eliminated by cleaning them if necessary., Rhodium-plated silver - a coating with a thin layer of rhodium (a platinum group metal) protects silver items from blackening and allows you to preserve the shine.
