Luster, the way a mineral reflects light, is the first thing to observe in a mineral. Luster can be bright or dull, but the most basic division among the various types of luster is this: Does it look like a metal or not?The metallic-looking minerals are a relatively small and distinctive group, worth mastering before you approach the nonmetallic minerals.
