Two common properties are:
1. Hardness — how easily a mineral is scratched, measured on the Mohs scale (talc = 1, diamond = 10). Example: quartz (hardness ~7) can scratch glass; calcite (3) is much softer.
2. Luster — how a mineral’s surface reflects light (e.g., metallic, vitreous/glassy, pearly, dull). Example: pyrite has a metallic luster; quartz is vitreous.
