Three minutes to learn: How does Hetian jade seed material distinguish true and false?

Dear friends, everyone. From the discussion of the previous articles, we basically found out the classification of Hetian jade and the distinction between true and false and Tian Yu. Now start to enter a higher level, more subdivided links. Today we will explore and learn: how to distinguish between true and false and Tianyu seed.

Hetian jade market phenomenon: There are many cases of Russian imitation seeds and mountain imitation seeds on the market, such as common sandblasting pores, mountain material rolling, artificial coloring, making fake leather, etc., and various kinds of counterfeiting methods are emerging one after another. Especially for novice buyers, they accidentally look at them. Therefore, Yu Mandian today focused on eight methods of identifying the naked eye seed.

Method 1: Surface observation

As is known to all, Hetian jade seed material is shaped like pebbles, the meat is fine and moist, the skin is smooth, and the gloss is strong. Due to the long-term transportation and scouring collision in the river, most of them leave collision pits and cracks of large and small (ten seeds). The allusion of the nine cracks is out of this). In the cracked place, most of them are filled with oxide, and some are oxidized to form a saccharide skin (the name of the oxidation surface). The appearance of the imitation seed material is not far from the seed material. The difference between the two is that the original skin color of the imitation seed material is frivolous and the gloss is poor. Especially the surface cracks and collision pits have traces of artificial processing, and the pores are very uniform. There are big differences in the unevenness and size of the natural formation.

Method 2: Reflective gloss observation

This method has a good test effect on the single seed or the Hetian jade stone. Observe the reflective surface of the jade against the sunlight or the light. Pay special attention to the corners. During the slow rotation process, observe whether there is no polished surface and no significant change in the gloss of Hetian jade. The real seed material will not have a polished surface. And the reflective gloss is uniformly changed. If it is a kind of imitation seed material, a clear polishing surface can be observed during the enlargement inspection, which is generally in the form of a line or a sheet, and the reflected light has a significant change during the rotation.

Method 3: Observation of collision pits

The smoothness of the surface of the raw material of Hetian seed material certainly cannot reach the level of artificial sanding. The smoothness of the original surface of the imitation seed material is very high. If the collision pit is not visible, it can be judged as fraud. If the collision pit can be seen, the gloss of the imitation seed material must be lower than that of the Tian seed jade.

Method 4: Observation of skin and meat

The raw skin and fleshy of Hetian seeds are next to each other. The skin color and pores of real seeds are formed after thousands of years. Just like spiritual animals, the flesh is connected. If you see a piece of skin and meat separated completely, there is no transitional "seed jade", then you have to wonder if it is imitation seed. The skin color of the real seed material will also have a little transitional color in the skin next to the skin. Of course, this should be observed in the cross section. Moreover, the more important true seed characteristics are that the pores and skin color will extend like a small nail to the meat next to the skin.

Method 5: Crack observation

Ten seeds and nine cracks, the original ecological seed material, its crack color will be a little deeper than the nearby color, but the color difference will not be very large, and it is a gradual transition. The color of the crack at the imitation seed material is very different from the color in the vicinity, and it is not completely smeared, and has a certain directionality. It is obvious that some people have traces of processing, and generally have a network structure. When buying the Hetian jade seed jade, the buyer should pay attention to observe whether the meat at the crack and the nearby meat has secondary dyeing. It can be inspected at the center of the crack, and sometimes it can be seen as granular. The particles are like the color dyed by the whole body. The color around the crack feels no penetration depth, and the edges of the color have a feeling of smearing and a feeling of suspension and surface (such as a lady's makeup).

Fake skin color will give people a feeling of superficial color, the most important thing is: the color is very bright, frivolous, no heavy feeling. Under normal circumstances, the cracks are darker in color, while others are shallow and there is no transition. The colors are sharply contrasted.

Cracks in artificial polishing materials are often just a simple line, and there are ochre in the lines. These ochre are generally light in the outer weight, and the seed material is just the opposite.

Method 6: Observation of impurity sites

Natural Hetian jade will be somewhat defective, such as cotton, cracking, structure, and black spots. Some merchants will get more profit in order to cover up these defects, and will dye in the defective part. Artificially colored Hetian jade seeds, merchants usually dye the whole body or leave only the parts with better local texture. The dyed color is darker, the color is bright and unnatural, most of the lines are clear, and sometimes it is linear.

Method 7: Observation of the glucocorticoids

The rind of Hetian jade seed material is the oxidation surface formed by the natural oxidation of Hetian jade iron. If the texture is different, the degree of penetration will not be the same, and the rind and meat will naturally fuse together. The rind in the Hetian seed material is present at the crack and the thicker part of the nearby structure. The syrup is more lustrous and the structure is finer.

Most of the imitation seed dyeing syrup is also colored at the crack or thick part of the structure. Since these places are easy to absorb the dye, the surface of the dyed syrup has low or no gloss, and many of them are rough, which is due to the dyeing process. Heating causes the loss of moisture.

There are also some laser-colored products, the texture of the whole material is very good, but the texture of the rind is coarse, and the surface of the granule is magnified to have an approximate particle shape. Some syrups have a strong gloss, and some syrups have a weak gloss. That is because the rind is not polished or dyed, and the rind is caused by fading during high-temperature polishing.

Method eight: touch

The natural Hetian seed has “pores”, so it feels awkward to feel, that is, the sense of resistance. It is because the force of human beings has a reactionary effect with the natural pores formed by the jade itself, thus forming a resistance. The roller and sandblasted seed material will feel smoother and smoother when touched, and it has a feeling of sliding hands.

Finally, the Yuman Hall is to say that the identification of Hetian jade seed material is more dependent on the “feeling”. The above-mentioned several identification methods need to be carefully understood. It is best to compare Hetian jade on hand and try to figure out more. In addition, the identification of the seed material should be considered in several aspects. Sometimes it is not one or two points to make it clear. In this era of anti-counterfeiting technology, the most important thing is to get started, compare and practice, and then accumulate more experience in seed identification, and then truly appreciate the mystery.
