How is jadeite identified? How to identify jadeite

The authenticity is mainly identified through gloss, color heel, and emeraldity.

**The evaluation is mainly based on the comprehensive judgment of the water, color, and weight of the workmanship.

You can go down, these are really not a sentence or two or even a day or two can be finished.

Weigh the jadeite.

It belongs to jadeite, the hardness is around the right, and there will be a feeling of "falling hand" when you put the jadeite in your hand. If it is too light, it is necessary to further identify the slippery side of the jadeite.

Listen to the sound Jadeite is dense, so it is also 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 a fake jadeite.

Look at the color of the barricade.

The color of natural jadeite is naturally layered, and the most obvious is the colored root of Jane chain 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.

Jadeite detection methods

1. Water support.

Jadeite is very water-supporting, we can drop a few drops of water on the natural jadeite, observe the direction of the water droplets, if the water droplets are very prominent, then the probability of real jadeite is greatly improved.

2. Surface structure.

The structure of natural jadeite is clear, and the better the water quality, the less obvious the structure. Even after polishing, the surface scratches and polishing lines are arranged in the same direction.

3. Identification by weight.

Because the density and proportion of the jadeite itself will be relatively large, we can put the jadeite in the hand up and down a few times, and feel that there will be a heavy downward pressure feeling, and there may be 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 downward pressure on the hand.

4. Identification by percussion sounds.

We can tie the jadeite with a rope, hang the jadeite in the air with a rope, and then gently tap the jadeite with an agate rod, and the sound of the real product is very crisp. If it is a fake jadeite, the sound made after striking it will be dull.

5. A bowl of water.

Connect the jadeite with the silk thread, place a glass of water on the precision electronic balance, and clear it; Place the jadeite in a cup and note the weight; Lift the jadeite with a silk thread, not exceeding the surface of the water, but always away from the bottom of the cup, again recording the weight. The weight of the jadeite in the water is divided by the weight of the water to get a value. If the value is between and , then congratulations, this jadeite is real.

Identification of jadeite can measure the hardness, look at the color root or use a thermal conductivity meter, the hardness of natural jadeite will not be scratched by a knife, when you light it with a flashlight, you can see that the color in the middle will be relatively heavy. If the jadeite is fake, the 5-bar light cannot be lit when testing the jadeite with a thermal conductivity meter.

1. Hardness can be tested to identify the authenticity of jadeite, jadeite is the hardest in jade, and its Mohs hardness is. Under normal circumstances, after scratching the surface of natural jadeite with a knife, no marks will appear. Imitation jadeite often does not reach this hardness and can leave obvious traces.

2. The thermal conductivity meter can also use the thermal conductivity meter to identify the jadeite, and the specific use method is to put the jadeite on the table, turn on the thermal conductivity meter switch after the stupid disturbance, and then put the metal contact at the top of the thermal conductivity meter against the jadeite. If the light on the thermal conductivity meter can be lit up 5 bars, it means that the jadeite is real.

3. To see the authenticity of the color root jadeite, you can also see the color root, the specific method is to turn on the flashlight and put it against the jadeite, and then observe the internal color of the jade ruler. If the color inside the jadeite is relatively strong, and the color gradually fades from the inside to the outside, it also means that the jadeite is real.

How to distinguish serpentine jade from jadeite?

Structural field balance characteristics.

The structure of serpentine jade is delicate, and there is no display of jadeite. Even under a microscope, the granular structure is not visible, and the orange peel effect generally does not appear on its polished surface.

Mohs hardness. Most serpentine jade has a low hardness on the Mohs scale and can generally be carved by a knife. But be aware that some serpentine jade can reach a hardness on the Mohs scale, which is greater than that of a knife and also greater than the Mohs hardness of glass, and can carve streaks on the glass.

Contains the characteristics of the wrestling house.

Serpentine jade often has white cloud-like clumps and various metallic minerals, such as black chromite and sulfides with a strong metallic luster.

Relative density. The relative density of serpentine jade is much smaller than that of jadeite, and it will feel that it is lighter by hand, and it can be accurately distinguished by weighing it with still water or heavy liquid.

Luster. The luster of the new jade is glass luster, the serpentine jade is the sub-glass luster, and the refractive index of the serpentine jade is about the same, which is lower than that of the jadeite.

Jadeite is a very valuable gemstone, so it is very important to identify a real slag jadeite. Here are some ways to identify jadeite: Color:

The color of the emerald should be a vivid green, but not too bright or too dark. The color of fake jadeite may be too uniform or appear gray, yellow, or brown. Transparency:

Jadeite should be translucent or opaque, not transparent. A higher level of transparency may be fake. Texture:

The texture of jadeite should be hard and textured, and there should be no cracks or bubbles. Feel the surface of the jadeite with your hands should be smooth. Pattern:

Jadeite often has a unique texture or pattern, which is a significant difference between real and fake jadeite. Fake jadeite is usually man-made and has no natural patterns or textures. Luster.

Jadeite should have a soft and even glow and not be too shiny or too dull. What is too shiny may be artificial. Density:

Jadeite should be heavier and denser. If it feels light, it may be a fake jadeite. Temperature:

Real jadeite is slightly cooler in the hand, while fake jadeite is warmer. Water drop test: put the jadeite in the gum machine or the palm of your hand, drop a drop of water on the jadeite, the real jadeite is not easy to absorb water, and the water droplets will form small droplets on the jadeite; Fake jadeite is easy to absorb water, and water droplets will quickly penetrate into the jadeite.

In conclusion, if you're not a professional, identifying jadeite can be a challenge. If you're buying expensive jadeite, it's best to ask an experienced professional or gemologist to help you identify the authenticity.

The identification of jadeite mainly depends on the texture, hardness, jadeite, relative density (specific gravity), etc.

Natural jadeite has a transparent or translucent texture with a shiny oily surface, and on closer inspection, you can see the nearly circular slightly transparent "salt grains" and the fibrous material that surrounds it. Natural jadeite is jadeite, Mohs hardness is 7 degrees, carved with a sharp knife, will not leave traces, fake jade hardness is low, sharp knife can carve out traces.

Natural jadeite is observed against strong light, and it can be seen that there are other mineral particles in the emerald flash, called emerald flowers or emerald, and counterfeit products made of glass, plastic, and porcelain do not have such "emerald" characteristics. The structure of natural jadeite is hard and tight, no bubbles, the density is large, and the sound is crisp when tapping; Counterfeit products have a loose structure or bubbles, less density, and a hoarse and uncrisp percussion sound.

Other identifications

In terms of color, the genuine emerald color is strong and pure. Some counterfeit products are made of white jade, serpentine, Australian jade, Korean jade, marble and even miscellaneous stones, after decolorization, poured into high-hard plastic pulp and colored, or immersed in green liquid to make "colored jadeite", observed under strong light, green lines can be seen, messy and fine. Although some do not show lines, they are turbid and have poor luster, and their weight is lighter than the real thing.

In general, the finished product of jadeite also has the luster of glass or sub-glass, their color is uneven, and it can also be viewed with the help of light or natural light, whether there are impurities or cracks in the body of jadeite, so that you can judge whether it is a good jadeite, and have a good standard for judging its quality.
