Physical Properties. The physical properties of minerals include: Color: the color of the mineral. Streak: the color of the mineral's powder. Luster: the way light reflects off the mineral's surface. Specific gravity: how heavy the mineral is relative to the same volume of water. Cleavage: the mineral's tendency to break along flat surfaces.

These minerals are defined to have precicely these hardnesses. Other minerals are equal to these values ONLY IF the index mineral can scratch the test sample and the test sample can scratch the index mineral. If a mineral has a hardness between two of these index minerals, it may be reported as between two values, such as hardness 4-5.

Mineral Properties. When you identify a mineral, you use clues gathered from your observations of its physical properties. The properties are things like color, density, and how hard the mineral is. In a general geology course, you would explore about 10 properties of minerals. For our purposes, we will focus on just a few.

Mineral crystals have shapes related to the arrangements of atoms within them. We typically use physical properties such as luster, color, diaphaneity, crystal shape, streak, hardness, and cleavage to identify and distinguish different minerals. Other properties, including magnetism and reaction to hydrochloric acid are sometimes diagnostic.
