Surface microtopography, representation and tracer of microscale vortex dislocation of hydrothermal synthetic sapphires and natural beryls are studied by using atomic force microscope and interference microscope. The research indicates that microscale vortex dislocation is another important growth mechanism of some gem crystals. It suggests that the vortex migration and crystalling phase vortex nucleation of microscale ore-forming fluid will be the another important way in which some matter in system of metallogenetic kinetics moves and exists. In this paper, the present situation and development of the research on growth mechanism of crystal are also discussed.
