Equipment

Under the excitation of deep ultraviolet ray, diamond and other gem materials will absorb energy and produce luminescence phenomenon. The phenomenon of gem being stimulated by light is called fluorescence effect. When the excitation light source is turned off, some materials continue to glow, which is called phosphorescence. The fluorescence and phosphorescence of baoyu stone materials reflect the structural characteristics. GV5000 is a professional equipment specially designed for observing the fluorescence and phosphorescence of baoyu stone materials
