  • Common basic characteristics/properties of minerals
    • Solid
    • Inorganic
    • Fixed chemical structure
    • Crystalline structure
    • Lustre
    • Hardness
  • Solid
    All minerals will be solids at normal temperatures on Earth
  • Inorganic
    Minerals do not come from plants, animals, or other living organisms
  • Fixed chemical structure
    Specific minerals will always have the same chemical formula
  • Crystal structure
    Minerals are generally formed with a crystal structure (they are crystalline)
  • Lustre
    Describes how well a mineral reflects light. Examples: glassy, metallic, brilliant, dull
  • Hardness
    Describes how easy it is to scratch the surface of a mineral. Diamond is the hardest, talc is the softest
