The Old School Process
The process is simple. The first step in testing gold to make sure that its solid, and not plated, is using a magnet. Any attraction to the magnet will tell you that the gold is either mixed with another metal or not gold.
​
The second step in testing is searching for the imprint stamp that will indicate what karat or grade the materials is. The last step would be to use the acid solutions once the material has been cleared in the first two steps.
