Luster, also known as shine or brilliance, refers to the way light interacts with the surface of a crystal, rock, or metal. The word "luster" is derived from the Latin word "lux," meaning "light," and is associated with radiance, gloss, and sparkle exhibited by watch materials such as the case, dial, and other components. The level of luster can vary depending on the materials used in the manufacture of watch components and contributes to the overall aesthetic appearance of the watch. Various finishing techniques, such as polishing and others, can enhance the luster and create a luxurious look for watch components.
