The percentage of pure gold and the value of a jewel do not depend on the color of gold, which is determined by the dosage of the other metals contained in the jewel, such as silver and copper. Moreover, it is possible to obtain different colors by adding very thin coatings of other metals to the surface of the jewel. For example, rhodium and ruthenium are used for this purpose.
