Though differentiate emerald method at present a lot of, differentiate through the instrument especially, detect not only fast, and accuracy rate is extremely high. But in trade it is a lot of and difficult that the instrument should be used to have in the process, when so consumer is buying halcyon, the most commonly used still is law of naked eye observation, nevertheless this method needs to accumulate much experience to just have effect, be deceived extremely easily otherwise, we differentiate a method with respect to what arranged halcyon of partial true and false today graphic, the hope adopts the comparative plan of halcyon of true and false, the understands halcyon of true and false distinction that makes everybody more intuitionistic.
