Specific gravity

A mineral's density relative to water: quartz 2.65, calcite 2.71, barite 4.5, galena 7.5, gold 19.3.

A mineral's density relative to water: quartz 2.65, calcite 2.71, barite 4.5, galena 7.5, gold 19.3. Measured by weighing in air and in water; the test that separates heavy minerals and meteorites from look-alikes.
