Violet jade is an excellent breed of jadeite family. It is very popular among the people. It is especially popular with young and middle-aged women.

The concentration of the color fades from the surface to the inside or to the sides of the fissure; if it is a natural color, the color is more uniform, and the colored roots, fissures, and loose spots. No accumulation. In addition, ultraviolet light (ultraviolet fluorescent light) can also be used for observation. The natural purple jadeite generally has no fluorescence reaction under ultraviolet light. The dyed purple jadeite often has more obvious fluorescence under ultraviolet light.

There are indeed artificially stained violet emeralds in the market, both in shade and in light. Purple dyes are generally manganese salts, and manganese ions (4-valent manganese ions) are responsible for the color of the emeralds. There is no reaction under the Charles filter.

Inspection by qualified personnel or a legally qualified inspection agency can ensure the quality of genuine and fake products. turn off.
