Can a mineral scratch a mineral with a higher hardness number or a lower hardness number? Lower number If a mineral is shiny, does that mean it is metallic or nonmetallic? Metallic An unknown mineral is pale yellow, shiny nugget. The mineral leaves a greenish-black streak, and cannot be scratched by fluorite. What is it? Pyrite An unknown metallic gray mineral leaves a gray streak. The crystals appear cubic. When it breaks, it breaks with clear, clean cleavage. It scratches gypsum. What is it?
