Density, reported in units of grams per cubic centimetre (g/cm 3), is a useful diagnostic tool in some cases. Specific gravity (SG) is a related measure that geologist’s use to describe the density of a mineral. For the purposes of this course, the specific gravity of a mineral can be described as “low”, “moderate”, or “high”.
