1, hot water immersion identification. We can put the jade in boiling hot water, and after a period of time, see if there is any discoloration in the water, or rub the jade with cloth to see if there is any discoloration. If it is really jade, it will not fade.

2. The identification method of jadeite is as follows: Look at the color root. Natural jadeite, especially green jadeite, has color roots. A color root is a place where green is thick, and then green will spread around the color root. Under the transmission of strong light, green will fade or disappear in some places, but the color root is still green.

3, look at the color: you can tell the authenticity of jade by looking at the color. Real jade is generally uneven in color, with cracks, which will transmit light, generally speaking, it is shallow in light transmission color. Fake jadeites are generally uniform in color. If there are cracks, it can be seen that there is artificial pigment deposition after light transmission, which leads to darker color.

4. Listen to the sound. When identifying jadeite, you can tap its surface gently first and listen to the sound made by jadeite.

Is it true that jadeite will have a fluorescent reaction when it hits purple light?

1. So jadeite that fluoresces under violet light is not necessarily fake, but it may be real jadeite, but it may also be what we call D jadeite, that is, jadeite dyed with green agate, quartzite, glass, jadeite and prehnite, and jadeite that has been impersonated after discoloration.

2. To sum up, if you start with a jade bracelet, it will fluoresce under purple light and you can never use it, then it is certain that this jade bracelet is not genuine, but a fake. These conditions mentioned above may also cause fluorescence reaction, which needs attention.

3. It can't be completely confirmed that jadeite purple light has a fluorescence reaction, because jadeite will use polishing powder in the polishing process, and the residue of polishing powder will have a fluorescence reaction, so it can only be said that jadeite purple light has a fluorescence reaction.

4. Under the violet light, some artificially treated jadeites will fluoresce, indicating that these jadeites have fluorescent agent residues, and jadeites with fluorescent reaction are not natural jadeites. Purple fluorescent jadeite is not necessarily a fake, but it can be guaranteed that it is not a good product.

5. 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.

What is the fluorescence reaction of fake jadeite?

Bottom line: Emerald with fluorescent reaction must be treated; Without fluorescence reaction, it can't be proved to be real jade. In fact, ultraviolet lamp is a sharp weapon to test fake jadeite, but it can't detect fake jadeite made of other materials.

Fluorescence reaction means that under the irradiation of ultraviolet lamp, the object emits blue or green light, which is fluorescence reaction. This is a phenomenon that can be observed with the naked eye.

The method of testing the authenticity of jade by purple light mainly depends on the color and internal structure of jade under the irradiation of purple light. 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.

When we irradiate with violet light, if jadeite has fluorescence 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.

How does purple light identify the authenticity of jadeite? Can the fluorescence reaction really identify the authenticity of 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.

Purple light 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.

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.

Drip identification method: drop a drop of water on the jade. If it is dewdrop-shaped, 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.

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.

Discrimination principle: Because natural stone will not have fluorescence reaction, natural jade will not shine under the irradiation of ultraviolet lamp.

How to see the fluorescence of a jade bracelet?

If jadeite has fluorescence, it can be irradiated with purple light. Some jadeites optimized by glue injection dyeing will have obvious fluorescence reaction under purple light, while natural jadeites will not have fluorescence.

Fluorescent jade, through the refraction of light, causes visual contrast to human eyes. Jade looks uneven in light and shade, and there will be a hazy, soft and faint light on the surface.

Shining is due to the high transparency of glass jadeite, which makes jadeite look crystal clear; Fluorescence is the fluorescence emitted by jadeite under ultraviolet fluorescent lamp and excited by external energy. Pay special attention here! Under normal circumstances, natural jadeite has no fluorescence.

In the identification and detection of jewelry and jade, the fluorescence effect of various gems is often detected by ultraviolet fluorescent lamp (or red light). If the fluorescence effect appears, it means that the gem has been treated artificially, which is one of the important characteristics of identifying and evaluating the gem.

Emerald has fluorescence, or is full of fluorescence, or gives off vivid fluorescence. This phenomenon often occurs on earrings, necklaces, Yu Pei and bracelets made of colorless ice or glass jadeite. The fluorescence of jadeite is different from that under the lamp.

When observing jade ornaments with high ice or glass, soft and hazy white light can be observed at the polished arc surface and attached to the arc surface. It feels like a thin layer of fog stays on your lens.

How to see the authenticity of jadeite with purple light?

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 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.

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 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.

5. To identify the authenticity of jadeite with purple light, firstly, the jadeite should be washed clean, and secondly, a dark place should be found, and the jadeite should be irradiated with purple light and observed. True jadeite is one that does not glow under purple light or only emits a little fluorescence. Violet light emits strong fluorescence, and the overall brightness is fake jade.

6. The method of identifying jadeite by purple light is not accurate, but it can be used as an auxiliary identification.
