What are the 4 characteristics of a mineral?

The four characteristics of a mineral are:

1. Cleavage- the way it breaks, whether flat or roughly.
2. Luster- the way light reflects off of it, i.e. pearly, shiny, etc.
3. Streak- the color that its powder is
4. Hardness, for example, diamond is the hardest mineral, this is usually measured on the Mohs scale.
