Give examples of four minerals that can be identified by unique properties. Describe each property.

Properties of minerals range from hardness to cleavage to color.

Quartz can be identified in that it has no cleavage, only fractures.

Calcite can be identified with a hardness of 3.

Topaz can be identified with a hardness of 8.

Fluorite can be identified as one of the only common minerals with 4 directions of perfect cleavage.
