The finish/luster of metals is rated on a scale from 1-7. What does a higher number represent?

A higher number on the scale indicates a higher level of polish or finish on metals. The scale is designed to measure the quality of the surface finish, where lower numbers correspond to less polished and rougher surfaces, while higher numbers reflect a shinier, smoother, and more reflective surface. Higher polish is typically associated with metals that have undergone extensive polishing processes, resulting in a more aesthetically pleasing and high-quality appearance. Thus, a higher number signifies that the metal has a finer luster and a greater degree of polish, making it more desirable for various applications where aesthetics and surface quality are important.
