1, Ziguang can't identify the authenticity of jadeite. The method of identifying jadeite by purple light is not accurate, but it can be used as an auxiliary identification.
2. The method of purple light to test the authenticity of jade: mainly depends on the color and internal structure of jade under purple light irradiation. Under ultraviolet light, real natural jadeite has no fluorescence reaction. Under the soaking of chemicals, a large number of resin chemicals remain in jadeite, and fluorescence will appear under the irradiation of purple light.
3. Ziguang cannot identify the authenticity of jadeite. The artificial jadeite is added with epoxy resin, which will emit fluorescence under the irradiation of purple light. However, the natural jadeite has not been treated, and there are many impurities in the stone, which will also have a fluorescence reaction under the purple light, so the purple light can't identify the authenticity of the jadeite. Distinguish between true and false jadeite, you can look at the color.
4. UV lamp can identify jadeite filling. Emerald on the market now is usually divided into four grades: A, B, C and B+C. The so-called A goods are what we often say about natural jadeite, B goods refer to jadeite artificially filled, C goods refer to jadeite artificially dyed under high pressure and high temperature, and B+C goods refer to jadeite both filled and dyed.
How does a purple flashlight identify the authenticity of jadeite?
Look at the cracks in the jade. The internal cracks of jade are irradiated, and the dark reaction or light change reaction with uneven refraction of the internal light source of jade is observed by translating the flashlight light source. Look at the internal structure and grain of jade. When the jade is illuminated at a 45-degree angle, the internal structure and stone grain direction of the jade can be clearly observed.
The method of identifying jadeite by purple light is as follows: If it is genuine jadeite, then under the irradiation of purple light, we will find that jadeite actually does not emit light, or a small number of jadeite will emit a small amount of light, but the light emitted is punctate.
Ultraviolet fluorescent lamp: purple light can be said to be a good helper to identify jadeite. Putting jadeite under purple light, natural jadeite has no fluorescence reaction. If it is dyed jadeite, it will have a fluorescent reaction. This method is especially effective for jadeite to dye purple, and purple jadeite has a strong fluorescence reaction under purple light.
What do you think of purple jade?
1, ultraviolet fluorescent lamp Look: purple light can be said to be a good helper to identify jadeite. Putting jadeite under purple light, natural jadeite has no fluorescence reaction. If it is dyed jadeite, it will have a fluorescent reaction. This method is especially effective for jadeite to dye purple, and purple jadeite has a strong fluorescence reaction under purple light.
2. When we irradiate with violet light, if jadeite has a fluorescent reaction, it must be fake jadeite, because this part of jadeite is actually artificially dyed in the later stage. This jadeite contains a lot of epoxy resin, which will fluoresce under the irradiation of violet light.
3. Ziguang can identify the filled jadeite, that is, the jadeite that can identify B goods. The jadeite with fluorescence reaction under purple light must be treated; Without fluorescence reaction, it can't be proved to be real jade. Ultraviolet lamp is a sharp weapon to detect jade counterfeiting, but it is impossible to detect jade counterfeiting from other materials.
4. When you look at jadeite with purple light, you need to observe jadeite under purple light. False jadeite generally has fluorescence reaction under purple light, while natural jadeite does not have fluorescence reaction under purple light.
5. The fake methods of jadeite include dyed jadeite, glued jadeite, colored jadeite and bleached jadeite. Among these fakes, dyed jadeite is the most common one. Generally speaking, we see that dyed jadeite is identified by purple light. How to identify the authenticity of jadeite with purple light Put jadeite under purple light, it is natural jadeite, and there is no fluorescence reaction.

Can purple light identify jadeite?
Violet can't identify the authenticity of jadeite. The method of identifying jadeite by purple light is not accurate, but it can be used as an auxiliary identification.
Violet can't identify the authenticity of jadeite. Artificial jadeite is added with epoxy resin, which will fluoresce under the irradiation of purple light. However, the natural jadeite has not been treated, and there are many impurities in the stone, which will also have a fluorescence reaction under the purple light, so the purple light can't identify the authenticity of the jadeite. Distinguish between true and false jadeite, you can look at the color.
Ultraviolet light can identify the filled jadeite. At present, jadeite on the market is usually divided into four grades: A, B, C and B+C. The so-called A product is what we often say about natural jadeite, B product refers to jadeite that has been artificially filled, C product refers to jadeite that has been artificially dyed under high pressure and high temperature, and B+C product is jadeite that is both filled and dyed.
Although ultraviolet light can't identify these D-grade jadeites, it can't be hidden in the certificate. If the certificate is not clearly marked with the words "Emerald (A)", be careful. Therefore, fluorescence reaction can only be used to exclude fakes, and it cannot be proved to be genuine.
The method of identifying jadeite by purple light is as follows: If it is genuine jadeite, then under the irradiation of purple light, we will find that jadeite actually does not emit light, or a small number of jadeite will emit a small amount of light, but the light emitted is punctate.
How to identify jadeite by ultraviolet rays
1, ultraviolet fluorescent lamp Look: purple light can be said to be a good helper to identify jadeite. Putting jadeite under purple light, natural jadeite has no fluorescence reaction. If it is dyed jadeite, it will have a fluorescent reaction. This method is especially effective for jadeite to dye purple, and purple jadeite has a strong fluorescence reaction under purple light.
2. The identification of true and false jadeite by ultraviolet lamp is mainly by observing whether jadeite has fluorescence reaction under the irradiation of ultraviolet lamp. Under ultraviolet light, natural jadeite has no fluorescence reaction. However, many artificially treated jadeites, that is, jadeites containing fillers such as epoxy resin, will fluoresce under the irradiation of ultraviolet lamps.
3, dripping identification method: drop a drop of water on jade, if it is dewdrop, it is real jade. Touch with both hands: If it is real jade, it feels cold and lubricated by hand. High-light observation method: Observe jadeite in high-light places, and the real jadeite is transparent in color and evenly distributed in green.
4. To identify jadeite with purple light, the first thing is to look at fluorescence. After the real jadeite is irradiated by purple light, there will be no reaction on the surface, or there will be extremely weak fluorescence reaction. False jadeite will have a strong fluorescence reaction after being irradiated by purple light.
5, jade washing, before preparing to identify with purple light, make sure the surface of the jade is clean. Find a dark environment, for example, choose to distinguish at night, shine purple light on jade, and see a fluorescent reaction, mostly processed.
6. Pickled and bonded jadeite becomes what we call B-grade jadeite or B+C-grade jadeite. True jadeite does not fluoresce under ultraviolet light, while epoxy resin as filler of B jadeite fluoresces under fluorescent light. Therefore, the jadeite dyed by pickling can be identified by purple light.
