How to distinguish the authenticity of jade? How to identify the authenticity of jade

Hello! Reliable ways to distinguish are: see, hear, test.

Look, mainly look at the crystal transparency, the real jade has strong transparency, and the grease is luster; Listen, Zhenyu's voice is crisp, on the contrary, the voice is hoarse; In the test, the real jade was scratched through the glass, leaving scratches on the glass, while the jade itself was not damaged in the slightest. Common fake jade includes plastic, colored glass, marble (marble), electric fake jade, jade made of jade powder and crystal and salt water, and jade imitated by glass, etc., and the means of identification are also different. The texture of plastic is lighter than jade, the hardness is poor, and it is generally easy to identify.

Coloring off-duty is also easy to distinguish. As long as you take it to the light or check it in the sun, you will see that there are many bubbles in the glass. It is more difficult to distinguish the electric color fake jade, which is plated to coat the inferior jade with a beautiful emerald green appearance, and it is easy to mistake it for real jade.

At this time, you need to observe carefully, if there are some small cracks with green and blue on it, it is fake jade. Because of the cracks left during plating, connoisseurs call them "spider claws". It is also said that if the electric color fake jade is placed in hot oil, the plating color will fade and its original appearance will be restored.

Synthetic jade made of jade powder, crystal and salt water is imitation dark old pit jade. The identification method is simple, i.e. they differ in specific gravity. The specific gravity of natural jade, while the specific gravity of artificial synthetic jade is only.

Weigh the weight by hand, or weigh it with a balance to distinguish the real from the fake. In fact, there are very few fakes on the market, but the quality of jade is good and bad, I wish you to buy real jade.

Some people say that the hair is tied to the jade and the hair of the jade is lit with fire, and the hair is constantly the real jade, and some people say that there is a knife scratching the jade, and the real jade is not afraid of scratching, and the fake jade has a crack (this cannot be tried).

Methods to identify the authenticity of jade include temperature, transparency, sound, dripping identification, looking at the structure, and so on.

1. Temperature. Jade is a beautiful natural mineral that is stony and has a cold texture. Put it in your hand and play with it, the real jade will have a cold feeling, it will become hot after a while, and it will become cold after being placed, while the fake jade will not feel cold in your hand.

2. Transparency.

Jade is mostly transparent or translucent, when the jade is placed in natural light, the real jade will produce a bright and transparent luster, put the hand behind the jade and shake it, the shadow of the hand is clearly visible. The fake jade has low transparency, and the luster will be gray and gloomy.

3. Sound. Tapping the jade with your hand, the real jade molecular structure is delicate and tight, and the sound is crisp and pleasant, while the sound of fake jade is dull and hoarse, and the sound is not as loud as real jade.

4. Drip identification method.

If a drop of water is placed on the jade, if it is a real jade that does not disperse for a long time like a dewdrop, the water droplet will disappear quickly and it is a fake jade.

5. Look at the structure.

Different jades have their own unique structure. For example, Hetian jade is a cotton-like structure, which can generally be observed with a strong flashlight or magnifying glass; The structure of fake jade is usually very neat or unrecognizable. Generally speaking, fake jade has a perfect appearance, bright color, clean texture, and no flaws.

Distinguishing the authenticity of jade mainly comes from the following aspects:

1. Distinguish from the texture. The texture of jade refers to the fineness and warmth of the jade. One of the differences between jade and stone is that jade is delicate, warm and firm, translucent, and lustrous like fat; The stone, on the other hand, is rough and dry, lacks luster, and is mostly opaque.

2. Distinguish from hardness. Hardness refers to the ability of jade to resist external forces such as pressing, carving, and grinding. The higher the hardness, the more difficult it is to process, and the better the quality of the jade.

Although the hardness index of jade can be known by detecting its internal crystal structure by instrument, the hardness method is generally used in operation.

The hardness of common jade in China is between 4 and 6 degrees, which is higher than the hardness of copper and lower than that of glass.

3. Distinguish from the luster. Luster is also one of the identifying characteristics of gemstones. It is also divided into four categories:

semi-metallic luster with a refractive index between, like goethite; Diamond luster, the refractive index is between, such as diamond; The refractive index of glass luster is between, such as jadeite; The oil is shiny, like animal fat, and the most famous is the mutton fat white jade in Hetian jade.

Each specific gem has a specific refractive index, and it is difficult to be consistent with the hardness, density, refractive index, and brightness of the substitute substance, so the identity and preliminary value of a gem and jade can be confirmed through the identification of these standards.

In general, it is not very difficult to distinguish the authenticity of jade.

One is to see if the jade quality is natural, if it is too transparent and there are no flaws, the possibility of fakes is relatively large; The second is to look at the color, the color is natural, not too uniform is true, otherwise the possibility of fakes is high; The third is that the "beautiful" and inexpensive jade is basically fake, and it is impossible for the seller to deal with his genuine goods at a cheap price; Fourth, the stalls and scenic goods are basically either fake or junk goods, and they must not be.

The jade and jade industry is very deep, and it is necessary to be cautious.

Look at the luster: whether the real jade is translucent or opaque, it has a warm luster, and it is normal to have a small amount of impurities or cotton wool-like patterns inside; The color of fake jade is dry, gray and dull, and there are bubbles.

Hardness: Carved and scraped with a knife, the real jade leaves no traces.

Specific gravity: real jade feels heavy, and fake jade is light.

Listen to the sound: hang the jade with a thread in the air, hit it with a hard object, the sound of the genuine product is crisp and pleasant, and the aftertaste is melodious; The fake ones are relatively dull and dry.

Look at the fracture: Observe with a 10x magnifying glass, the fracture of the real jade is uneven, and the relatively fine structure can be seen; The fracture of the fake jade is neat and shiny, and it is often a glass imitation, and the fracture structure is rough and there is no waxy luster.
