It is clear that the real seed material actually has to be fake leather.

In recent years, with the increasing depletion of Xinjiang Hetian jade seed resources, and the market's pursuit of seed materials, its price has skyrocketed, even ten times that of Hetianshan and other regions. This has further led to the fact that the market for counterfeiting of Hetian jade seeds is becoming more and more common, especially in the case of the second epithelium of Hetian seed material, which is the easiest for buyers.

What is the second epithelium of Hetian jade seed material? The second epithelium refers to the case where the Hetian jade seed material has been washed with raw skin, and then dyed on the surface to make fake skin. Since it is a real seed, why do you want to make a second skin?

There are many reasons for this, but the main reason is to cover up the defects on the poor quality seed so that it can be sold at a higher price. For example, there are some kinds of seeds, except for the parts with the skin, the quality of the meat exposed outside is very good, but there will be some impurities on it, then the merchant will make a layer of fake leather to cover these defects, only to keep very The perfect fleshy portion continues to be exposed, allowing the piece to be sold at a higher price.

So how do we identify the Hetian seed that has undergone a secondary epithelium with poor quality?

The most important method of identification is to observe the skin color of the seed. Because artificial dyeing takes a short time and does not have a long weathering process, it has characteristics that are quite different from natural skin color.

1, the color floats on the surface

Observing the natural skin color with a magnifying glass or a microscope, it can be seen that both the Fenghua and the iron infusion are not only present on the surface, but also deep into the seed meat. The color of the fake leather floats on the outside, not as deep as the natural color.

2, no change in depth

On the same piece of white jade seed, the color of natural iron impregnated material is uneven, with deep and shallow changes, distinct layers, and a certain distribution law, that is, from the inside to the outside: black-dark red-brown-yellow-light yellow excessive. Black is often spotted in the center of the infusion. The artificial leather has a single color, generally no shade change, and no natural skin color, from the inside to the outside, from black to yellow.

3, without weathering associated

Generally, the natural skin color is opaque, pale yellow or white, distributed in a band along the crack, or irregularly agglomerated or spotted in a weak structure. The counterfeiter dyes the original white stone flower in the jade to pretend to be a natural weathering, but the stone flower and the jade meat are clear and there is no intermediate excessive phenomenon.

Although the seed material of the two epithelium is also a true seed material, its internal structure has been damaged due to pickling, so the jade and luster are not as good as natural seed materials, and because of the chemical substances, Not too good for the human body. I hope that players can open their eyes when buying Hetian jade seed materials, think twice before they go, and never be willing to take advantage of it.
