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

The identification method of jadeite rough is as follows:

1.Look at the crystal size of the leather: soak the jadeite gravel with water and then take it out to see if there is any water evaporating from the skin. The volatilization is fast, indicating that the crystal is coarse, the structure is loose, or the original stone has many cracks, many cracks, and poor texture.

2.Strong light: Under strong light or sunlight, use opaque metal cards or lamps to observe the hue around and inside the leather shell, the direction of green, the change of luster, and the strength of the reflection.

The color of the real jadeite rough is bright and natural, the green direction is clear, the luster is strong, the reflection is bright, and the surrounding part is a gradient relationship, the fake rough stone tone is gray, unnatural, the green direction is irregular, the luster is weak, and the reflection is dark.

3.Listen to the sound: When identifying the real and fake jadeite rough, you can also distinguish the real from the fake by the sound.

Listen to the sound with a hard object. It is recommended to use an agate rod to gently tap a few times to hear a crisp and melodious sound, while most of the artificially treated jadeite rough will destroy the internal structure, resulting in a relatively low sound.

4.Weight: Jadeite rough is a fibrous aggregate composed of pyroxene minerals dominated by jadeite minerals, and the weight of jadeite rough is slightly heavier than other jade, and the heavier it is, the higher the density.

It is recommended to find a professional to help identify!

1. How to identify the authenticity of the jadeite rough is as follows: Shine: With a flashlight or under natural light, the face of the jadeite rough is easily exposed. The naturally formed jadeite rough has a gorgeous luster and is natural, in which the green direction is very clear and the luster is strong.

2. Identification of jadeite rough can be seen by color, structure and luster. The color of the natural jadeite original wheel is from the inside out, the color distribution is regular and natural, and the internal structure is tight and orderly, which can show a glass luster. Artificially treated jadeite, on the other hand, is unnatural in color and often exhibits a resinous or waxy luster.

3. The real jadeite rough has a bright and natural color, obvious green trend, strong luster, anti-brightness, and a gradient relationship with the surrounding parts. The fake rough is gray, the color is unnatural, it is irregular green, the luster is weak, and the reflection is dark. Listen to the sound:

When identifying real and fake jadeite, you can also distinguish the real from the fake by sound.

4. Look at the natural color of the jadeite rough stone, the color on the shell is full, and the color of the artificially treated jadeite rough shell is different. When identifying real and fake jadeite rough, you can distinguish it by looking at the color.

5. First, surface features. The color of natural jadeite is pure, and the transition section is obvious. If it is a fake jade, the color will be more cloudy. The surface of natural jadeite has a strong vitreous luster or sub-glass luster, while the luster of false jadeite is oily or waxy.

6. Distinguish the authenticity of the jadeite rough with strong light, the natural jadeite rough Bu Tong will show a gorgeous and natural color under strong light irradiation, the green direction is clear, and the surrounding part is a gradual relationship. The fake jadeite rough has a gray and unnatural tone, irregular green direction, weak luster, and dark reflection.

To identify the authenticity of the jadeite rough, you can look at the color, strong light, listen to the sound, touch the leather shell, weigh and other methods.

1. Look at the color.

The color of the natural jadeite rough is uniform and translucent, and the color on the shell is full, while the color of the artificially treated jadeite rough shell is different. When identifying real and fake jadeite rough, you can distinguish it by looking at the color. The color of the natural jadeite rough is uniform and translucent, the color on the shell is full, it looks like it gives people a fresh feeling, the green part of the incision is bright and bright, and the color of the artificially treated jadeite rough shell is different, it looks unnatural, and it is easy to fade.

2. Strong light.

Under strong light or sunlight, the color of the real rough stone is bright and natural, the green direction is clear, and the color of the fake rough stone is gray and unnatural, and the color is unruly and cautious, and the luster is weak. Natural jadeite has jadeite, you can use a strong flashlight to see the jadeite rough, if you can see the surface of the rough shining jadeite particles, this is jadeite, is a major feature of natural jadeite.

3. Listen to the sound.

When identifying real and fake jadeite rough, you can also distinguish the real from the fake by sound. Listen to the sound with a hard object. It is recommended that you can use an agate rod to tap lightly a few times to hear a crisp and melodious sound, and most of the artificially treated jadeite rough will destroy the internal structure, resulting in a lower sound than Kuanzi.

4. Touch the leather shell.

The leather shell has the unique natural arrangement of grains of the jadeite leather shell, the texture is hard, in addition to the mountain material, there is the phenomenon of mineral particles peeling off by hand rubbing, the water stone skin shell is solid, it is difficult to peel off the hard object knocking, the sound is crisp and the color is natural, the structure is uniform, if there is a change and the surrounding part has no obvious boundary, there is a gradual relationship with cracks and later fillings, representing the product of multi-stage geological action.

5. Weigh the weight.

Jadeite rough is a fibrous aggregate composed of pyroxene minerals dominated by jadeite minerals, and the weight of jadeite rough is slightly heavier than that of other jade, and the heavier it is, the higher the density.

How to identify the jadeite rough is really as follows:

Jadeite rough is a precious gemstone that is loved for its unique green color and brilliant brilliance. However, due to the large differences in the texture and value of jadeite rough, it becomes an important issue to identify the authenticity of jadeite rough. Here are some ways to identify the authenticity of jadeite rough stuffy pants:

1. Appearance judgment: The appearance of real jadeite rough shows obvious luster, showing layers of multi-layer textures, while fakes show different textures and traces. In addition, genuine jadeite rough weighs heavier, while fakes weigh less.

2. Sound judgment: When beating the jadeite rough, the real jadeite rough has a crisp sound, while the fake makes a dull sound.

3. Refractive index judgment: The refractive index of jadeite rough can be determined by a simple test. The refractive index of a genuine jadeite rough is around the right, while the refractive index of a fake is different.

4. Density judgment: The density of jadeite rough is higher than that of other stones, and the density of the jadeite rough of the real ant key is about the same, while the density of the fake is different.

5. Judgment of mineral composition: The mineral composition of jadeite rough is complex, mainly composed of jadeite, omphacite and sodium chromium pyroxene. The proportions of these components in a real jadeite rough should match the composition of the jadeite.

6. In addition to the above methods, you can also use some auxiliary tools to identify the authenticity of jadeite rough. For example, use a fiber optic lamp or flashlight to irradiate the jadeite rough to observe its internal structure and color distribution; Use a microscope to observe the surface and internal structure of the jadeite rough; Use a specific gravity solution (usually water) to measure the density of the jadeite rough, etc.

In addition, it can also be tested and identified by professional institutions, such as jewelry testing institutions, geological laboratories, etc. These institutions use advanced technology and instruments to conduct comprehensive testing and identification of jadeite rough, and the results are accurate and reliable.

In short, identifying the authenticity of jadeite rough Liangye requires a combination of methods and tools. When using these methods and tools, it is necessary to pay attention to the correct handling methods and details to avoid misjudgment or damage to the rough. At the same time, it is advisable to understand the relevant knowledge and experience before conducting any appraisal to avoid unnecessary losses.

Some merchants will glue high-quality jadeite shells on the surface of waste rocks and substandard materials, and then cover up the traces of artificiality after a series of chemical treatments, and disguise them as natural jadeite roughs. There are also some merchants who will make an incision in the rough jadeite of poor quality, and then paste a thin sheet of high-quality jadeite on the incision, making people mistakenly believe that there is high-quality jadeite under the shell. In addition to these two methods, jadeite rough counterfeiting also uses bright color, dyeing to make fake colors, or making fake hearts.

When we buy jadeite rough, we must first clean it with clean water, and then carefully inspect its skin shell after cleaning, including some subtle cracks, small holes, and even changes in particle size. Secondly, for jadeite rough with incisions, we must carefully check whether there are traces of bonding on the edges of the incisions, whether the shape of the gaps is normal, etc. In addition, for the colored part, it is necessary to observe whether the color is natural, and whether there are traces of dyeing such as dense color at the crack.
