How to identify the authenticity of jadeite, how to identify the authenticity of jadeite

Identification of jadeite jade.

Observe for impurities. Since jadeite is formed in nature, if it is a cargo, there will inevitably be some impurities, such as black, yellow or gray body, while the treated B carousel has few impurities because it is corroded by strong acid.

Emerald roots. Look at the color root. The so-called color root refers to the fact that in jadeite jewelry, there is a little or a thin strip of slightly darker green, and these slightly darker greens gradually transition into a relatively light green called color roots.

The color of natural jadeite A goods is natural and generous with the bottom, and the green color is distributed like tree roots or clumps, with clear and clear contours. The color root of the treated B jadeite is blurred and unclear, and the color and the bottom are as muddled as a Chinese painting, showing spots, black spots or fragmented floating. Most of them show this green on gray or bean green ground.

Look at the gloss. A goods gloss is generally strong glass luster. The luster of B goods is dull, generally looks waxy or resinous luster, the surface and shallow part are more transparent, and the further you go inside, the more cloudy it becomes.

Look at the surface. Looking at it with a high-powered magnifying glass, the surface of the A goods is smooth and delicate, and it can be seen that different mineral particles show fine concave and convex and particle junction lines on the surface due to the difference in hardness. For a product with poor texture, grooves caused by poor polishing usually only appear in local locations, especially in recesses that are not easy to polish.

The surface of the B cargo is disorganized, the lines are straight and uneven, showing spider webs and dendritic grooves, and the surface has an orange peel-like structure due to the difference in hardness. Handle strong B goods, with cracks on the surface.

Identification by weight. The density and specific gravity of the jadeite itself will be relatively large, you can put the jadeite in the hand and move it up and down a few times, and feel that there will be a heavy downward pressure feeling, and there is a real jadeite with this feeling. When the fake jadeite is in the hand, it will be a light and fluttering feeling, and there is no feeling of downward pressure.

That's right.

Summary. Hello, happy to answer for you! Trick 1:

Look at the luster natural jadeite (A goods jadeite) has a typical glass luster, the naked eye has a bright and moist feeling, and after glue injection and bleaching treatment of jadeite (B, C goods, etc.) The surface of the jadeite is resin luster, the luster is dull, and even waxy texture, without rigidity! "Vitreous luster" is the basic basis for visual identification of jadeite. Tips for identifying jadeite luster:

When observing, swing the jadeite back and forth, left and right, and feel the intensity and uniformity of the reflection of the jadeite through the reflected light on the surface. I hope I can help you. <>

<> trick 2: Look at the structure through the identification of the luster of the jadeite, and the authenticity can not be determined, then the jadeite structure 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.

Techniques for identifying "fly wings": 1. Observe on the reflective surface of jadeite; 2. The observation part should try to avoid the part that is better to throw; Note that some kinds of jadeite with high quality water have delicate flesh and tight crystal structure, so the phenomenon of "fly wings" is not obvious, but their glass luster will be very obvious, so the naked eye judgment is to be comprehensively evaluated, not a single one!

Trick three: look at the color of jadeite is rich in color, the color is beautiful and colorful, which is also one of the directions for us to identify the authenticity of jadeite with the naked eye, the color of natural jadeite is uneven, accompanied by color roots. 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.

In general, the three stunts of connoisseurs to identify jadeite with the naked eye are "glass luster", "fly wings" and "color roots". According to the combination of these three characteristics to determine the authenticity of jadeite, grasp these three points, through more contact with jadeite practice, you will also be easy to distinguish the authenticity of jadeite at a glance.

1. The method of distinguishing the authenticity of jadeite: color touches the root. The color root is a little or a thin strip of slightly darker green, and in these colors, the darker green gradually transitions to a lighter green.

The color of the stove or natural jadeite A goods is natural and generous with the bottom, and the green is distributed like tree roots or clumps, with clear and clear contours. Emerald sex.

2. According to the color, density, glossiness, convex and concave degree of the skin, the color inside the jadeite raw materials, the quality of the water head, the quality of the ground, the age and tenderness of the species and the number of cracks can be roughly estimated.

3. Look at the gloss. Swing the jadeite left and right in the sun, carefully observe the luster of the jadeite surface, identify the authenticity of the jadeite, natural jadeite has a good glass luster, the luster is not very strong, and the jadeite after artificial dyeing and glue injection treatment has a strong resin luster. Fluorescence reactions.

Hidden quarrels. 4. Purple lamp irradiation to identify the authenticity of jadeite is to use a purple lamp flashlight to irradiate it to see if there is a fluorescent reaction of jadeite.

5. Identification of the authenticity of jadeite can be carried out by listening to the sound, testing the hardness, comparing the weight, looking at the defects and seeing whether the jadeite certificate is held. Here's what it looks like: Listen to the sound.

The way to identify jadeite is to look at the luster, structure, color, hardness and texture.

1. Luster. The surface gloss of natural jadeite is very high, generally based on glass luster or grease luster, and the overall appearance is relatively bright and moist, while the fake surface is mostly waxy luster, which looks much duller and has no rigidity.

2. Structure. Under the illumination of the light, it can be seen that there are often some fibrous or flocculent structures inside the natural jadeite, that is, fly wings, which are unevenly distributed, while the fake ones do not have these, and they look relatively clean.

3. Color. The color of jadeite is rich and diverse, the color is gorgeous, under the observation of strong light, it can be seen that the obvious color root, the transition color is more natural, and the false color seems to only float on the surface, evenly distributed, easy to fade.

4. Hardness. Jadeite is a typical representative of jadeite, which is hard and dense in texture, and does not change much after being carved on it with a knife, while fake ones are prone to scratches after being carved.

5. Texture

The texture of natural jadeite is delicate, it feels very tactile to the touch, and gives people a cold feeling, while the fake texture is very poor, and its temperature changes with the change of the environment.

Jadeite can be authentic and false from color, transparency, luster, hardness, weight, ice species, etc.

1. Color. True jadeite comes in a variety of colors such as green, white, purple, etc. But the most prized is the emerald green color that has a rich and uniform color. Care should be taken to avoid colors that are too bright, too bright, or too dull, which may be characteristic of dyed or other jadeite imitations.

2. Transparency.

Jadeite usually has some transparency, but it should not be completely transparent. Real jadeite will have some internal textures, textures, impurities, or subtle inclusions. Overly transparent stones may be materials such as artificial stone or auspicious coder glass.

3. Luster. The luster of jadeite is usually warm and soft, reflecting a unique oily luster. If you see a shiny or dull sheen, it may be a man-made material or other imitation.

4. Hardness. Jadeite is comparatively higher in hardness, and its hardness score is between. You can try to scratch the surface of the jadeite with a less hard object, such as a steel needle, and the real jade will not be scratched.

5. Weight. Real jadeite is usually heavier, heavier than other imitations in the same volume.

6. Ice species. Ice is a special texture effect in jadeite, which exhibits a uniform, delicate and transparent texture. Some imitations may mimic the effect of ice seeds, so you need to take a closer look at the naturalness and uniformity of the texture.

Through the following 6 methods, you can easily distinguish the authenticity of jadeite:

1. Identification by weight.

2. Look at the color roots. Natural jadeite, especially green jadeite, has colored roots.

3. Identification by percussion vocalization.

4. Identification by the color and gloss of the surface.

5. Use a magnifying glass to look at its facet.

6. Look at the appraisal report will look at the appraisal report, when buying jadeite, you must ask the seller for the jadeite appraisal certificate, and judge the authenticity of the jadeite through the jadeite appraisal certificate.

Answer yourself at home can use a toothpick to gently drip water on the jadeite, the real jadeite will bear the water into dewdrops, and the fake jadeite water will slide down. You can also use a hard object to hit the jadeite to listen to the sound, the sound of the real jadeite is crisp, and the sound of the fake jadeite is dull. Or use a knife to scratch the jadeite, the real jadeite will not leave traces when cut by the knife, and the fake jadeite will leave scratches or even severe damage.
