Luster and composition are two characteristics used to classify minerals.
What can be shiny or pearly is a minerals luster.
A waxy luster gives minerals a shiny appearance.
Scientists classify minerals based on their chemical composition, crystal structure, physical properties, and chemical properties. This classification helps them understand the characteristics of different minerals and how they form in nature.
The Mohs scale uses the hardness of minerals to classify them from 1 to 10. It was named after the German geologist Carl Friedrich Christian Mohs.
