The specific gravity of gold is 19.32. Specific gravity is determined by dividing the weight of the material by the weight of an equal volume of water. Gold also has a melting point of 1950 degrees Fahrenheit and it weighs 10.18 troy ounces per cubic inch.
If the gold is not pure, then it will have a different specific gravity, melting point and weight. For example, 18-karat green gold has a specific gravity of 15.9, a melting point of 1810 F and a weight of 8.375 oz t. Another variation is 10-karat red gold, which has a specific gravity of 11.59, a melting point of 1760 F and a weight of 6.106 oz t.
