The specific gravity of diamond is 3.5, which is 'above average'.
Specific gravity of corundum is between 3.95-4.01.
Water has a Specific Gravity of 1. Silicate mineral rocks have specific gravities from 2 to 4, generally. The answer is True.
There is no such thing as a specific gravity for any element.
Aluminum has no specific gravity, at least by the current definition of gravity.
