Identification method of jadeite fluorescence How to identify jadeite fluorescence

1. In fact, fluorescence in jadeite is an optical phenomenon used to describe jadeite. When shaking Yuhuan, a colorless ice seed, a soft, white and hazy white light can be observed, just like the feeling of the moon when a thin cloud swims at night.

2. The fluorescence of jadeite is an optical phenomenon to describe jadeite, which can be simply understood as self-luminescence formed by its own refraction effect without external strong light irradiation, so the fluorescence of jadeite belongs to a diffuse reflection light system.

3. It is particularly emphasized that in addition to good materials, the device type is also very particular, and the shape of the arc surface is needed to achieve the fluorescence effect. No matter how good the material is, it can't shine if it is made into a flat shape like nostalgia. Fluorescence refers to the appearance of dyed jadeite under specific light, and natural jadeite A goods do not have fluorescence.

4. The identification method of jadeite polished with fluorescent powder is as follows: Observe with a purple flashlight, the light source is about 10CM away from jadeite, and hit from bottom to top, and you can see that the surface has been polished with fluorescent powder. Put the jadeite jade under the purple light money detector, and you can see that the surface has been polished with fluorescent powder.

5. Structural identification. Under the irradiation of flashlight, crystal substances such as monosodium glutamate and salt may appear in natural jadeite.

6. The "fluorescence" in the fluorescence of jadeite is an optical phenomenon used to describe jadeite. "Luminescence" is also called "cold light", which can be simply understood as self-luminescence formed by self-refraction of jadeite in the absence of external strong light, and it is a diffuse reflection light system.

What do you think of fluorescence in jadeite original stone?

1. Look at the texture and thickness of jade: in the process of electric translation by direct shooter, the light transmittance of jade is uniform, indicating that the structure is uniform and the light transmittance is uneven, indicating that the structure uniformity of jade is uneven.

2. See 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.

3. Fluorescent jadeite, through the refraction of light, gives the human eye a visual contrast. Jade looks uneven, and the surface will have a hazy, soft and faint light.

4. Jade will fluoresce, which is an optical phenomenon. Another popular saying is that a piece of jade refracts light, which makes the whole jade uneven in light and shade, causing visual contrast to human eyes. The stronger the fluorescence, the more obvious the contrast.

How to treat B jade bracelet under the light? B what does the jade bracelet look like in the light?

1, please click to enter the picture description structure: under the light, the structure of goods A is clear, the structure of goods B is fuzzy, and the cotton inside also gives people a sense of divergence.

2. Look at the fluorescence of the jade bracelet. You can use ultraviolet rays. When the jade bracelet is irradiated by ultraviolet flashlight, if the jade is treated by chemical means such as pickling, glue injection and dyeing, the jade bracelet will produce fluorescence reaction.

3, lighting to see the jade bracelet, generally use a jade flashlight. If you don't look at the original jade stone, you can also light it with your mobile phone. Looking at the jade bracelet with light mainly depends on the texture of the jade, whether there are cracks, flaws, impurities, etc., so as to judge the quality of the jade bracelet.

4. The naked eye can see that there are acid pits on the surface of B brand jadeite bracelet, and reticular acid corrosion is a typical surface feature of B brand jadeite. Looking at the light again, we can find that the structure is loose and not dense, there is no mineral structure, there is no emerald, and the color roots float.

5. structure. The jadeite raw materials that can be used to make jadeite B goods are generally jadeite with more impurities and loose structure. After being soaked and corroded by strong acid and alkali, some substances are brought in and brought out, and dissolved between the surface and internal crystals along the ore, resulting in internal connected cracks and surface system of canals, and the internal cracks are serrated tensile cracks.

How to turn on the light to see the glued jadeite?

The identification methods of glued jadeite include boiling in water, looking at it with a magnifying glass, looking at its luster, irradiating with violet light and listening to the sound. Boil in water. Boil jadeite in cold water until it boils. If the texture becomes more and more turbid, even jadeite will fade.

One obvious feature of the glued jadeite is that the appraiser can see it just by looking at it! It is said that when watching bracelets, with purple light, those bc bracelets will be exposed to light. However, some friends asked her about this. She said she couldn't see it after reading it for a long time.

The third type: look at the cracks. It can be said that if there are bubbles in jade, it will stick to it in nine cases out of ten. Natural jadeite has a high hardness, and obvious concave grooves can be seen at its cracks. If these fillers are mixed into the gaps after glue injection, staggered ditches with bubbles will be formed.

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.

Jadeite is irradiated with purple light, and if there is a strong fluorescence reaction, it is a glue-injected jade. Boil jadeite in cold water until it boils, and the texture becomes turbid and even the color becomes pale. Observing the surface structure with a magnifying glass, the structure is irregular, and there are more jadeite injected in the fracture.

How to treat jadeite fluorescence?

1, jadeite gives off fluorescence, which is an optical phenomenon. Another popular saying is that a piece of jade refracts light, which makes the brightness of the whole jade uneven and causes visual contrast to the human eye. The stronger the fluorescence, the more obvious the contrast.

2. See 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.

3, radian, fluorescence depends on the refraction of light, so the performance of fluorescence is also affected by the shape, angle and radian of jade itself. If the shape of a piece of jade is relatively flat and there is no radian, the performance of fluorescence can hardly be seen. So the pendant will carve some spheres on the edge to highlight the fluorescent effect.

4, fluorescent jade, through the refraction of light, the visual contrast caused to the human eye, jade looks uneven, and the surface will have a hazy, soft and weak light.

5. The identification of jadeite fluorescence can be identified by purple light, and the treated jadeite will have obvious fluorescence reaction under purple light. When jadeite is excited by external energy (ultraviolet rays, etc.). ), it produces luminescence, and the luminescence stops immediately after the excitation source is vacuumized. This luminous phenomenon is called fluorescence.

6. Next, let's use the actual illumination map to see the illumination performance of jadeite rough stone in different kinds of water: the glass has fluorescence, looks full of taste, and has a strong metallic luster, which is what experts call "fluorescence".

How to see the fluorescence of jadeite?

You can see the fluorescence of jade bracelets with ultraviolet rays. When you irradiate the jade bracelet with an ultraviolet flashlight, if the jade is treated by chemical methods such as pickling, glue injection and dyeing, the jade bracelet will have a fluorescent reaction.

Emerald emits fluorescence, which is an optical phenomenon. In other words, a piece of jade refracts light, which makes the whole jade uneven in light and shade, causing visual contrast to human eyes. The stronger the fluorescence, the more obvious the contrast.

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.

In fact, the fluorescence of jadeite can be irradiated by purple light, and the treated jadeite will have obvious fluorescence reaction under purple light, while the natural jadeite has no fluorescence reaction. It can also be observed in natural light. Light blue fluffy thin lines can be seen on the edge or pattern of jadeite, but natural jadeite does not have this feature.
