I'm not sure but I belive that it is hardness
The crystallographic axes of minerals are expressed as numbers. As such these numbers can also be used to describe the orientation of mineral cleavage planes. The Mohs hardness, specific gravity, and melting point of minerals are also properties that can be expressed numerically.
yes it is

I think its Specific Gravity :)
Density, boiling point, melting point, concentration etc...
Minerals can be recognized and distinguished based on physical properties such as color, luster, hardness, cleavage or fracture, specific gravity, and crystal habit. These properties can help in identifying different minerals as they each have unique characteristics that can be used for classification.
yes it is
Some properties of minerals that can be expressed in numbers include hardness (using the Mohs scale), specific gravity (a ratio of the mineral's weight to the weight of an equal volume of water), and refractive index (a measure of how light bends as it passes through the mineral).

The stripe, and color
They are the properties that are unique to certain minerals such as flourescence or radioactivity
I think its Specific Gravity :)
