How To Test If Gold Is Real | Test Methods |

· The Float Test. Another easy method of testing gold jewelry or bullion at home is the float test, for which you need to place your gold piece in a cup of water. Due to gold's high density ( g/ml), pure gold will immediately sink to the cup's bottom. Fake or plated gold will hover or float above, while gold alloys will tilt up halfway.
