Mineral Luster and Color

The video tutorial by Professor Dave covers mineral identification focusing on luster and color. It explains how luster, either metallic or non-metallic, helps in identifying minerals. Non-metallic lusters include adamantine, vitreous, pearly, silky, resinous, greasy, and dull. The tutorial also discusses how color, influenced by transition metals and structural defects, can be misleading and how the streak test provides a more reliable identification method.
