How to distinguish the real from the fake between jade and jadeite? How to distinguish the real from

The easy way to do this is:

One is to look at the color. Color is the most important factor in evaluating the quality of jade. The jade with a uniform, yang, dense and positive color is the top grade.

"Uniform" means uniform; "Yang" refers to the bright color, giving people a cheerful and non-depressed feeling; "Thick" means that the color is darker; "Positive" means that there are no other variegated colors mixed together.

The second is to look at the texture. Jade is a polycrystalline mineral formed by silicates at high temperatures and pressures, and the size of the constituent crystals will directly affect the smoothness, transparency and hue after grinding. Therefore, the finer the polycrystalline structure, the better the texture of the jade.

The third is to look at transparency. Transparency is a physical phenomenon that complements texture. The finer the texture, the higher the transparency. If jade is as transparent as glass, the fineness of the crystals inside it allows the light to penetrate without being blocked.

The fourth is to look at the acquired processing. When jade is mined, it is just like ore, and the colored parts of the stone must be carefully cut into different ornament shapes by experienced professional craftsmen, then processed, polished, carved, polished and waxed before it can reach the market**. Those that have not been bleached, faded, or dyed at all during processing are rated "A" and have the highest value; The bleached and faded ones are rated "B", followed by the value; The dyed "C" grade is of lower value.

Excellent acquired processing can make jade icing on the cake and multiply its value.

Five look at the cracks. Cracks on jade can be caused during mining or processing. Once you have a crack, no matter how good its color, texture and transparency, it will affect its value.

Sometimes the crack is not noticeable on its surface, but it can be seen when you look closely in the sun. Especially for jade that has been bleached, faded or dyed, cracks are common.

While identifying the quality of jade, it is also necessary to prevent artificial imitation jade from being fake and real. Artificial imitation jade is made of dyeing glass, plastic and other materials. Most of the glass imitation jade contains bubbles, the color is bright, the green has a strong brightness, and the color is different from the real jade.

Plastic imitation jade is lighter than real jade, with very poor transparency and dull tone, which is far from real jade.

The following is an introduction to the advantages and disadvantages of jade, and the method of distinguishing between true and false

Water identification method A drop of water is dropped on the jade, such as a dewdrop, the real jade that does not disperse for a long time; The droplets disappear quickly are counterfeit goods.

Hand touch method If the real jade is touched by hand, there is a feeling of cold lubrication.

Inspection method Orient the jade to the light, such as sunlight and light, if the color is clear and the green color is evenly distributed, it is the real jade.

Tongue licking method The tip of the tongue licks the real jade, which has an astringent feeling; Fake jade, on the other hand, has no astringent feeling.

Magnifying glass** Put the purchased jade under the magnifying glass**, mainly whether there are cracks, those without cracks are high-quality jade, and those with cracks are secondary. Even if it is a real jade, the value of the cracks is greatly reduced, and the more cracks and the more obvious the value, the lower the value. Good luck and good luck!

Jade jadeite can be distinguished from the real by observation.

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. 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.

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.

Precautions for buying jade jadeite

Good jadeite of course to have a kind of water color standards, to meet these standards of high-quality jadeite will have a lot of money, in reality we encounter jadeite often only one of them, or the head of the water is good, the color is slightly inferior, or the color is good, the head is slightly worse, at this time you need to choose according to your own preference to plant water or color, generally speaking, should first look at the color of the water, if you encounter a few can choose, use the standard of choosing the boutique to measure, choose the closest to the boutique jadeite.

The most taboo in jade is cracks, when we buy, we should use lights or flashlights to fully inspect the jadeite, once cracks are found, try to give up. If a piece of jadeite has cracks, its value will be greatly reduced.

1. When there is an internal crack in the crack, there will be an ordinary dark reaction of the flashlight source when the flashlight source is translated, or there will be an uneven refracted light change reaction. The correct way to see the structure is to light at an angle of 60-70 degrees, so that it is easier to see the structure clearly. According to the structure of the material, determine what material it is, whether it is natural or synthetic.

2. Identify real and fake jadeite: First, first obliquely look at the light to see if there are small holes on the surface of the natural light, and if there is a fake, it is really smooth. Second, if you use a toothpick to dot a drop of water on the surface of the jadeite, the real water will hang on it like dewdrops, and the fake one will not hang water.

Be sure to wipe the jadeite clean before inspection.

3. Wrap the hair around the jadeite and burn it underneath with a lighter or candle, if the hair is burned, the jadeite is fake, and vice versa. You must know that even if the thermal conductivity of jadeite is good, it cannot withstand the burning of the flame outside the flame, so this method is unscientific in the identification of jadeite.

4. Jadeite jade distinguishes the real from the fake by weight only stupidity. Because the density and proportion of the jadeite itself will be relatively large, we can put the jadeite in our hands and stare at it a few times, and feel that there will be a heavy downward pressure feeling, and it may be the real jadeite with this feeling.

5. The easiest way to distinguish the authenticity of jadeite jade is to screen through the naked eye and experience, and touch and verify the surface of jadeite jade. Although this method is simple, it requires the screener to have many years of experience.

6. Distinguish the authenticity of jadeite jade by looking at impurities, listening to the sound and weighing the weight.
