What are the methods of identifying jadeite, and can you introduce it?

1. Texture. The texture of natural jadeite is transparent or translucent, the surface is oily and shiny, and if you look closely, you can see that it is slightly transparent in a nearly circular shape"Grains of salt"and the fibrous substance that surrounds it. Jadeite can be seen to be partially hazy or patchy through the light, while glass imitations do not have these characteristics, and no matter how well this imitation is done, there will be bubbles.

2. Hardness. The hardness of jadeite is very high, and the sharp knife will not leave traces when carved and scratched. Jadeite can scratch glass, and it is doubtful if it can't scratch any traces.

3. Emerald nature. Natural jadeite is observed against strong light, and it can be seen that there are emerald-colored flashes of other mineral particles in it, which is called emerald flower or jadeite; Counterfeits made of glass, plastic, and porcelain do not have this"Emerald sex"Features.

Fourth, the specific gravity. The proportion of jadeite is heavy, and there is a feeling of heaviness in the hand, while the glass imitation looks light and fluttering.

Fifth, workmanship. It is best to use a magnifying glass of more than 4 times to see, some jadeite finished parts, species, water, color may not be very good, but the fine workmanship can also improve the collection value of jadeite.

In addition, you can also use professional jewelry identification equipment for professional identification.

For example: gem refractometer, gem microscope, ultraviolet fluorescent lamp, beamsplitter, etc. Like these instruments, I know that there is a "magic weapon fable" brand in Shenzhen that is doing well. Very professional.

Now jadeite in the market usually use the letters A, B, C as the identification to distinguish the texture of jadeite products. A goods: natural jadeite raw materials of finished products.

Its texture and color have not been artificially altered, maintaining its natural nature. B goods: dirty, gray and black, dry, green or dark jadeite raw materials or semi-finished products, artificial chemical and physical treatment, C goods:

On the basis of the treatment of B, the colorless or light-colored jadeite is artificially dyed into a gorgeous and beautiful color. This is in.

Looking for it, there are some specific methods to understand, which is very practical.

There are three ways to identify jadeite: 1. Listen to the sound, the real jadeite will make a crisp and pleasant sound when percussion, and the fake sound is dull and dull; 2. Feel the feel, the real jade feels cold and refreshing in the hand, and the fake feeling is mild; 3. Look at the jadeite, the real jadeite has a fly wing-like flash on the surface under natural light, and the fake one does not have this characteristic.

1. Listen to sounds.

When you gently tap the surface of jadeite with chopsticks, the structure of natural jadeite is dense, and it will make a crisp and pleasant sound after tapping. The fake jadeite has a loose structure and will make a slightly dull and dull sound when tapped.

2. Feel the feel.

Jadeite can also be identified by feeling the feel, when the jadeite is pasted on the ** or held in the hand, the natural jadeite gives people a feeling of being cold and refreshing, while the fake jadeite gives people a relatively mild feeling.

3. Look at the emerald nature.

Jadeite can also be identified by looking at jadeite, when the jadeite is placed in natural light to observe, the surface of the natural jadeite will appear fly wing-like flash, which is the unique jadeite of jadeite, and other jade, gemstones do not have this characteristic.

The identification methods of jadeite are: color identification, fire method, hot water immersion method, listening to sound, weighing weight, etc., which are introduced as follows

1. Color identification.

There is such a mantra in the industry, "strong yang and pretty and harmonious, light yin and old evil flowers". "Thick" means that the color of jadeite is dark green, but not black; And "light" is to play sensitive, which means that the green color is light. "Yang" means that jadeite is bright in color and bright in luster; And "yin" means that the green color is not bright.

"Qiao" means that the green color appears crystal clear; And "old" is not good. "Positive" means green and pure; And "evil" refers to the color of yellow, cyan, blue, gray, and black in green. "And" means that the green is evenly arranged, while "flower" means that it is flawed.

2. Fire method.

Put the jadeite on the Kai branch of the flame hall to bake, generally speaking, the fake jadeite will have the phenomenon of fading, and the real jadeite A cargo thermal conductivity is very strong, there will be no change!

3. Hot water immersion method.

As the name suggests, the jadeite is soaked in hot water, and then the surface is wiped with an alcohol cloth to see if the color will fade, which is also one of the very practical ways to identify the authenticity of jadeite!

4. Listen to sounds.

Hang the jadeite in the air, and then gently tap it with a wooden stick, if it is a real jadeite A goods, the sound is very crisp and melodious, and the sound of fake jadeite will be slightly dull!

5. Weigh the weight.

Jadeite belongs to jadeite, the hardness is around the right, and the jadeite will feel like a "falling hand" when you weigh it in your hand. If it is too light, it is necessary to further identify other aspects of the jadeite.

Summary. Hello: 1. Look at the certificate, the real jadeite will have an identification certificate, if there is no fake jadeite; 2. Weighing the weight, the density of natural jadeite is large, and there is a sense of heaviness when weighed, while the fake jadeite is a light and fluttering feeling; 3. Listen to the sound, you can hear a very crisp sound when you hit the natural jadeite, and the fake jadeite is a dull sound.

Summary. 1. Look at the color: you can distinguish the authenticity of the jadeite by looking at the color, the general color of the real jadeite is unevenly distributed, there are cracks, cracks will transmit light, and the color of the light is generally lighter.

Fake jadeite is generally more uniform in color, if there are cracks, it can be seen that there is artificial pigment deposition after light transmission, resulting in a darker color. 2、..

1. Look at the color: you can distinguish the authenticity of the jadeite by looking at the color, the general color of the real jadeite is unevenly distributed, there are cracks, cracks will transmit light, and the color of the light is generally lighter. Fake jadeite is generally more uniform in color, if there are cracks, it can be seen that there is artificial pigment deposition after light transmission, resulting in a darker color.

The easiest way to identify a jadeite is as follows:

1. Weight: Jadeite belongs to jadeite, with a hardness of about 7. Putting the jadeite in your hand and weighing it will have a feeling of "falling hand". If it is too light, other aspects of the jadeite need to be further identified.

2. Listen to the sound: jadeite has a high density, so it is brittle. When identifying jadeite, you can use an iron rod to gently tap the jadeite to hear whether the knocking sound is crisp and pleasant. If the sound is low and not brittle, then it is likely to be counterfeit jadeite.

3. Look at the color: The color of natural jadeite is naturally layered, and the most obvious is the colored root of jadeite. Counterfeit jadeite is difficult to do, because the internal structure of counterfeit jadeite is destroyed after artificial treatment, the color inside the jadeite will be mixed together unnaturally, and the color will be yellowish.

4. Look at the luster: the refractive index of jadeite is there, so the luster will be similar to the luster of glass and have rigidity. After being soaked in strong acid and alkali, the internal structure of counterfeit jadeite is loose, resulting in diffuse reflection, showing resin luster and lack of spiritual texture.

5. Purple light: Counterfeit jadeite is soaked in chemicals, and a large number of resin chemicals are stored inside the jadeite, and when illuminated by the purple lamp, it will fluoresce. With the upgrading of imitation methods, some counterfeit jadeite cannot be detected even by this method.

Precautions for buying jadeite

1. Observe the cracks.

Some cracks are not clear to the naked eye, so it is best to use a magnifying glass when buying jadeite, so that you can see the situation inside the jadeite.

2. Pay attention to variegation.

Variegated refers to some dirty spots inside the jadeite, which will make the whole jadeite jewelry look very incongruous, such as some black spots or brown spots are not allowed, except for some special varieties, such as sprinkled gold jadeite or black chicken jadeite.

3. Don't be impulsive.

Novices are easy to impulsively consume when they see their favorite jadeite, in fact, the jadeite bought in this way is usually higher than the normal **, and when you see the jadeite you like, you should pay attention to strategy, so that you can use the lowest ** to win your favorite jadeite.

Hello, the easiest way to identify jadeite is as follows: 1. Look at the luster swinging jadeite left and right in the sun, carefully observe the luster on the surface of the jadeite, and identify the authenticity of the jadeite. Natural jadeite has a good vitreous luster, and the luster is not very strong.

The jadeite after artificial dyeing and glue injection treatment has a strong resin luster. 2. The internal structure of the jadeite is observed from the reflective surface of the jadeite under the sun, and the internal structure of the jadeite is seen, and there will be dots or flakes on the surface of the natural jadeite, similar to the shape of a fly's wings. In places where natural jadeite is not polished well, there is a high chance of fly wings.

3. Fluorescence reactionIn a relatively dark environment, use a purple lamp to irradiate the jadeite to see if the jadeite has a fluorescent reaction. Generally speaking, natural jadeite has a better color under the irradiation of purple light and does not fluoresce. The artificial jadeite after artificial dyeing and glue injection will have a strong fluorescence reaction and appear blue-purple color.

4. The appraisal of the institution is directly sent to the jade appraisal agency with national certification qualification for appraisal, and the appraisal jade appraisal certificate can be issued in about three days. On the front of the appraisal report, there will be the words "jadeite grade A" and "jadeite grade B", jadeite grade A refers to natural jadeite, and grade B refers to jadeite after pickling.

Trick 1: Look at the luster

Natural jadeite (A jadeite) has a typical glass luster, with a bright and moist feeling to the naked eye, while the surface of jadeite (B, C, etc.) after glue injection and bleaching treatment is resin luster, dull luster, and even waxy texture, without rigidity! "Vitreous luster" is the basic basis for visual identification of jadeite.

Identification of jadeite luster skills: when observing, swing the jadeite back and forth, left and right, and feel the reflective strength and uniformity of the jadeite through the reflected light on the surface.

Trick 2: Look at the structure

Through the identification of the luster of jadeite, the authenticity cannot be determined, so the structure of jadeite must be identified. To look at the structure of jadeite, the first thing to see is whether the jadeite has the phenomenon of "fly wings". The phenomenon of "fly wings" is what we call jadeite, which is the sign of jadeite, and is an important basis for the identification of connoisseurs by the naked eye.

Trick 3: Look at the color

The color of jadeite is rich and colorful, which is also one of the directions for us to identify the authenticity of jadeite with the naked eye. In particular, the most precious green color is generally distributed in various forms such as dots, veins, filaments, patches, etc., accompanied by colored roots. Colored must have roots, which is one of the effective characteristics of identifying jadeite.

Identification of "color root" skills: observe the color on the jadeite, analyze the color distribution, look for the color**, if the color appears out of thin air or only appears in the cracks, it is mostly dyed jadeite.

Summary. 1.Observe the appearance of jadeite:

Jadeite can be in a variety of different colors, such as dark green, pale green, light green, brown, etc., and its surface can have smooth textures or patterns. 2.Hand touching jade:

Jadeite has a warm surface, colder than metal, and warmer than other stone types. 3.Wipe the jadeite with a scrub cloth:

The surface of jadeite has a pattern, which will be more obvious after rubbing, while the surface will become smooth after rubbing with ordinary stones. 4.Burn the jadeite with fire:

Emerald emits a faint smoke, while ordinary stone emits a thick smoke. 5.Wipe the jadeite with something sharp:

The surface of jadeite has a thin layer of wax that produces fine white fragments on the surface after wiping, while there are no white fragments on the surface of ordinary stones after wiping.

The easiest way to identify a jadeite.
