Metallic luster is a shiny, reflective appearance exhibited by metals and some minerals. It is characterized by a high degree of reflectivity and a mirror-like surface. This luster is a result of the way light interacts with the free electrons in the metal's atomic structure, causing it to reflect light in a unique way that gives it a metallic sheen. Metals like gold, silver, and copper are well-known for their metallic luster. **
