Specific Gravity of Minerals . Specific gravity is the density of a material, in this case a mineral, compared to an equivalent volume of water. If a piece of galena has a specific gravity of 7.58, that means that it is 7.58 times heavier than a volume of water identical to the volume of that particular piece of galena.Specific Gravity is approximately 7.5+ (heavy even for metallic minerals) Streak is lead gray Associated Minerals are calcite, dolomite, sphalerite, pyrite and other sulfide minerals, also lead oxidation minerals such as cerussite and anglesite. Other Characteristics: brighter metallic luster on cleavage surfaces than on crystal faces.

A complex pattern of electrons between the two forms of iron is the source of its magnetic nature. Although other metallic minerals may mimic magnetite’s color, luster, hardness and specific gravity, magnetite is the only common mineral that is magnetic.
