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

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 break:

Observed with a 10x magnifying glass, the fractures of the real jade are uneven, and a 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. If you don't invite experts, first-time jade players should identify the authenticity of jade by themselves, which can be observed from three aspects: 1. Because the glass texture is very brittle and hard, the structure is arranged and dredged, and the density and toughness of jade are lacking, and it cannot withstand strong high-speed rotary carving, so it is generally not processed on the glass with high relief and round carving.

Second, use a magnifying glass to find bubbles, even if you can only see one, you can confirm that it is not jade. 3. Chromium oxide is added to the glass, and the color is close to ruby; Cobalt oxide is added, and the color is nearly sapphire; Chromium oxide and copper oxide are added to give the color to the ...... of emeraldsAnd so on, and so on, and there are many kinds of fake jade. However, their tones always appear thin, lacking the oily and rich feeling of natural jade.

Identify the authenticity of jade

1. Look at the luster of jade: different qualities of jade have different refractive indexes, which leads to great differences in the luster of jade. The surface of natural jade has a clear grease luster, although some impurities and patterns in it are also normal.

The luster on the surface of the fake jade is relatively dim, and the overall appearance has no aura, giving people a dull feeling.

2. Look at the color of jade: Most of the fake jade is counterfeited from the color aspect. So if you want to distinguish the authenticity of jade, you can use a magnifying glass to carefully observe the jade.

The color of real jade is different, and there is no pattern in the distribution of colors. The color of fake jade is mostly bright, and the color distribution is more even, and the color transition looks unnatural.

3. The weight of the jade: The real jade has a certain sense of weight in the hand, and the weight is very sufficient. The weight of fake jade in the hand is very light, because most of the fake jade is made of glass, and the specific gravity of the glass itself is lighter than that of natural jade, so if the weight of jade is very light, it must be fake jade.

4. Listen to the sound of jade: If you want to distinguish the authenticity of jade, you can prepare a wooden rod or metal rod to knock on the surface of jade. If the sound is crisp and loud, it is real jade, and if the sound is low, it is fake jade.

There are four ways to verify the authenticity of jade, as follows:

1. Jade usually has the feeling of pressing the hand, especially the jade with a large weight, and the glass of the same volume is placed on the left and right hands respectively, and the jade will have a heavy feeling.

2. Carefully observe whether its hue is too bright, if so, it is also mixed with a variety of hues, most of which are dyed or baked, and you need to be vigilant.

3. Due to the high density of jade, the percussion sound should be relatively crisp, and if it is glass or other products, the percussion sound with a hard object will be significantly different.

4. You can feel the temperature of jade, and you will feel cold when you are close to **, and there will be a temperature close to the human body after about three seconds. In cases where the authenticity is not known, this method can be used to test.

Identifying the authenticity of jade involves a variety of systematic knowledge, which cannot be finished in one or two sentences. If you want to learn in detail, it is best to learn it systematically, and it is estimated that it will take a few years to get started.

1.Listen to the voice.

How to distinguish the authenticity of jadeite?

The authenticity of jade can be discerned by listening to the sound, gently tapping it with metalwork or glass. Natural jade will make a crisp and pleasant sound, while imitation jade will make a dull and mute sound.

2.Look at the color.

How to distinguish the authenticity of jadeite?

The color of the jade can also be seen from the fake. The color of natural jade is pure and bright, and it will show a greasy luster in the sun. Imitation jade, on the other hand, is rich and saturated in color, with a gelatinous texture on the surface, lacking the nature and vitality of natural jade.

3.Measure hardness.

How to distinguish the authenticity of jadeite?

The authenticity of jade can also be determined by measuring its hardness. Take a knife or glass block and lightly scratch the surface of the jade. The surface of natural jade will not produce any cracks and marks, while the surface of imitation jade will have deep scratches.

How to distinguish real and fake jade :

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.

The jade imitated with glass looks whiter and smoother than jade. The ancients said: "Jade is bound to be high."

That is, white jade must be like a glass to be considered high-grade. It can be seen that it is difficult to distinguish between glass and jade. However, truth and falsehood are different after all.

In terms of color, white jade is often bluish in white, and there are very few pure whites, while glass is pure white with uniform whiteness. As far as jade is concerned, jade is warm and delicate, like fat and paste, although the glass is also warm, it is inevitable that there will be thief light in the moist. White jade is a natural product, and it is difficult to have a uniform physique, including jade tendons and jade flowers.

If the glass is artificially made, there is no such appearance. The white jade texture is firm and there are no bubbles to be found. No matter how well the glass is processed, there are often bubbles and air holes exposed.

If you figure out these items, you won't think of glass products as jade.

The identification of jade mainly depends on whether the color is strong (rich), yang (distinct), pretty (beautiful), positive (pure), and (soft). On the contrary, if the jade is light (plain), yin (dark), old (dark), flower (impure), oblique (uncoordinated), it is inferior. Do not choose jade under strong lights, because the light will make the jade lose its original color.

It will also cover up flaws and confuse the real with the fake. When buying jade, you also need to learn to distinguish the authenticity. Common fake jade includes plastic, glass, marble, electric color and so on.

The texture of plastic and marble is lighter than that of jade, and the hardness is poor; Tinted glass has bubbles; Electric fake jade is a layer of beautiful and dazzling emerald green coated on inferior jade, which is difficult to identify at first glance, but on closer inspection, electric inferior jade often has some "spider claws", that is, small cracks with blue in the green.

What you said is too general, jade is divided into jadeite and nephrite, jadeite generally refers to the jadeite we usually bring, nephrite is Hetian jade, serpentine jade, etc., you first determine what jade you want to identify.

Real jade weighs the same as stone, and it feels smooth and moist to the touch, and it feels very good.

If you don't know how to speak, you should find an expert, because the identification of jade is a very difficult thing, and experts will also lose their eyes!

Soak in the water to see the color fade, don't knock it, it's a stone, don't scratch the glass, you can scratch the glass, no.

This is very professional, not something that can be explained in a few sentences, generally the more expensive the more true.

Strictly speaking, there is no truth or falsehood in jade, as long as it is good or bad, I personally think that the most important thing is pure color.

Take the jade to scratch the glass to see if the jade is damaged.
