Teach you to identify if the jade is violet
We can use the following two methods to identify whether the jadeite is violet. First, you can use a magnifying glass to observe the characteristics of the purple distribution to identify the jadeite: if it is artificially dyed, the concentration of the color will fade from the surface and to the sides of the crack and the color will infiltrate along the micro-cracks of the jade, and there will be accumulation in the loose structure. . If it is a natural color, the color will be more uniform and there will be no accumulation in the loose place. Secondly, the jadeite is identified from the perspective of the dye. The artificially dyed dye is generally a manganese salt, and the jadeite colored by manganese ions (tetravalent manganese ions) does not substantially react under the Charles filter. However, it can be observed by means of ultraviolet fluorescent lamps: the dyed purple jade will produce more obvious fluorescence under ultraviolet light; while the natural purple jade will generally not have a fluorescent reaction under ultraviolet light.
