Gold has a density of about 19 g/cm 3; pyrite has a density of about 5 g/cm 3 —that's another way to tell pyrite from gold. Quartz is even less dense than pyrite and has a density of 2.7 g/cm 3. The specific gravity of a substance compares its density to that of water. Substances that are more dense have higher specific gravity.
