A real diamond disperses the heat instantaneously so by the time you look at it, it has already cleared up. (Sometimes oil and dirt on the stone can effect its reliability and the test is not accurate at all on doublets where the top of the stone is diamond and the bottom is cubic zirconia epoxied together.)
