Minerals are an essential part of our daily lives, from the construction of buildings to the production of electronics. One of the most fascinating aspects of minerals is their luster, which refers to the way they reflect light. In this article, we will explore the minerals that have a shiny luster and their unique properties.
What is Luster?
Luster is the way a mineral reflects light. It is determined by the way the mineral's surface interacts with light waves. Minerals with a shiny luster reflect light in a way that creates a metallic or glassy appearance. This is due to the presence of free electrons on the surface of the mineral, which allows it to reflect light in a unique way.
