💎They used in space satellite laser detectors that exhibits two different colors, red and green, under ordinary light, without the need for ultraviolet radiation. When ultraviolet light is irradiated, it emits red light, but the red light is not evenly distributed in it, but changes with the angle of irradiation, even if its material is uniform and completely transparent under normal light.💎
These crystals why known as "Christmas gemstones" because they appear in both red and green colors.
