How to Identify the Authenticity of Jade How to Identify the Authenticity of Jade,

How to identify 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.

How to identify the authenticity of Hindustan jade.

Under normal circumstances, the choice of Zndustan jade is mainly based on the jade material, shape and ornamentation. In terms of jade, the dark gray jade used and the jade material similar to Chinese jasper are its own unique jade species. Jasper is characterized by uniformity and a lighter pattern.

The white jade used is the best white jade material in Xinjiang. In terms of shape, the Hindustan jade is mainly shaped by olive-style bowls and cups. And this is rare in the Chinese jade-making tradition.

In terms of its ornamentation, the most obvious feature of the jade is that it is influenced by the local climate and natural conditions, as well as customs, and the ornamentation on the utensils is mostly passionflower patterns and Shaoliang flower patterns. These are also endemic plant species.

Fluorescence identification 1) Natural jadeite generally has no fluorescence, which"White cotton"Some have light yellow fluorescence.

2) Jadeite B goods, most of which are filled with organic glue, generally have blue-white fluorescence (filling wax also has blue-white fluorescence); There are many on the market today"Eighty-three jade"Bracelets and pendants (B goods) have uniform and strong blue and white fluorescence. Some B goods are non-fluorescent, and may be filled with silica gel (?). and other substances.

3) Most dyed jadeite on the current market has no fluorescence (the same as natural jadeite); However, some have significant fluorescence. Certain fluorescence features are useful for identification, such as a strong yellow-green fluorescence dyed with green jadeite (dyed with this green, which has a shorter storage time, and the green fades to yellow), and a dyed red with strong straw yellow fluorescence.

Percussion sound The percussion sound cannot be used as the basis for judging jadeite A and B goods. Some jadeite sellers often use two bracelets to strike lightly to produce a crisp"Steel"The sound indicates that it is natural jadeite, and the impact sound of the jadeite B goods filled with obvious is slightly dull. But issued"Steel"The sound is not necessarily natural jadeite, such as diopside (such as Qinghai jade), amphibole albite (such as Burma"Water foam"jade) and so on"Steel tone"。

Some of the B goods that appear on the market today can also be issued crisply"Steel"Sound.

Reticulated jadeite rinsed with strong acid generally has obvious pores and reticulated structure. The stress and weathering of natural jadeite can produce obvious pores and reticulated structures, which are often difficult to distinguish from the reticulated cracks caused by acid corrosion. "Those who observe cracks, pittings and pits must be b-goods"The opinion may not be appropriate.

Therefore, the author recommends removal"No glue B goods"concept. The natural pores of jadeite can be filled with zeolite, clay minerals, etc. in the later stage; In the process of cutting, grinding and polishing, it can also be filled with mineral powder or polishing powder. These fillings are not considered B goods and are easy to identify.

Identification problem In accordance with the provisions of the national standard "GB T 16552-1966 Jewelry and Jade Name", on the test report and commodity label, jadeite B goods and C goods must be marked after the name"(Processing).", such as:"Emerald bracelet (handled)."。Considering that the value of colored jadeite is much lower than that of goods A and lower than that of goods B, it is more deceptive; Through market transaction surveys, on product labels or test certificates"(Processing)."The word, some operators interpret as:"Optimized processing"or"Backlog"、"Price reduction processing"Wait. Jewelers at home and abroad feel that jadeite B and C goods have a huge impact on the jadeite market, and the majority of merchants who operate natural jadeite jewelry hope to clearly mark jadeite B and C goods; From the perspective of consumers having the right to know, in order to make it easy for consumers to understand, it is recommended that when the national standard is revised, whether to consider whether to directly mark the glue injection and dyed jadeite jewelry"Injected jadeite xx"、"Dyed jadeite xx"、"Injection dyeing jadeite xx", such as:"Rubber-injected jadeite bracelet"、"Dyed jade Guanyin"、"Injected with glue dyeing jade Buddha"Wait.

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.
