Lithium has a high luster when a solid sample of the pure metal is inspected. But it quickly tarnishes in air as it reacts with water vapor and other things. Lithium is quite reactive, and that makes its shine disappear quickly unless something is done to preserve it. Stored under an inert oil or in an inert gas atmosphere, it will retain its luster.
