Solid
A state of matter that maintains its own shape instead of conforming to the shape of its container.
Liquid

Color
Its what light reflects back to our eyes. minerals are colored because they absorb some colors of light reflect the rest.
Luster
How shiny a rock or minerals is looks when light shines on it, like a mirror, or glassy, or even dull. (Luster is a physical property used by mineralogist to help identify minerals).
Cleavage
How some minerals break along smooth, flat lines instead of randomly, like when you crack a egg
