Answer to Question 1

Cleavage is a natural break along a plane of weak bonding within a mineral's crystal structure. Cleavage will result in smaller pieces of the mineral, all with the same geometry as the original crystal. Fracture is a break that results from a mineral having relatively equal strength bonds in all directions that make up its crystal form. Consequently, all the products of fracture are different and irregular or conchoidal shapes.

Answer to Question 2

Color is frequently not a diagnostic property for mineral identification because tiny impurities in the mineral's chemical composition can influence or dramatically change the mineral's color. Fluorite, for example, can be yellow, clear, blue, or purple.
