Even if alchemy does not exist, electroplating can be considered the next best thing. The idea is to coat relatively common metals (e.g. copper, steel, etc.) with a more precious one (e.g. gold, silver, etc) using electricity! Actually electroplating has many different uses, besides making cheap metals look expensive. Indeed, it can be used to make anti-corrosion coatings, to produce a variety of alloys like brass or bronze on steel, etc...
