Gold can easily be distinguished from "fool''s gold" by specific gravity alone, although there are many other ways. Specific gravity is a unitless measure, because it is derived from the density of the mineral divided by the density of water and thus all units cancel.
Specific gravity of some common minerals and other materials
Because ore grades of 30 ppm are usually needed before gold is visible to the naked eye, in most gold mines the gold is invisible. The average gold mining and extraction costs were about 317 per troy ounce in 2007, but these can vary widely depending on mining type and ore quality; global mine production amounted to 2, tonnes.
