Ten kinds of fake techniques of jade original stone

For the identification method of jade original stone, it must have rich jade knowledge and have the eyesight to identify authenticity. It is very useful for jade stone lovers to master the correct identification method of the original jade stone.

Ten kinds of fake techniques of jade original stone

First, fake leather

There are many reasons for this kind of fraud, and the deception is also large. The reason for the fraud is nothing more than covering the essence of the jade to achieve the purpose of deception. The method of making a fake is to smash some weathered layers of the jade husk, and then some quartz sands are glued to the surface of the jade stone. Therefore, it is soft and gelatinous, and there is no natural arrangement of fine grains. This is the biggest feature of fake leather.

Second, false color

This type of dyeing method mainly includes plating, ochre or fire. In many places, the identification is the same as the identification of the jewelry, but in some indications, it is not available in the jewelry. For example, the green color present in the original stone is immersed in the table. The green color tone always has a blue and yellow taste, and some burnt focus of different sizes can be seen on the surface layer. These yellow spots are caused by corrosion of acid and alkali. It is easy to find signs of falsification as long as they are carefully observed during the identification.

Third, true and false color mixing

This kind of fake behavior is not only found in the original stone, but also often seen in jewelry. At the same time, it is also a deceptive and extremely difficult artificial phenomenon. The purpose is to increase the amount of green or add dark tone. These colors are characterized by the former, but they are difficult to coexist in the identification due to the combination of true and false.

Fourth, the imaginary class

In the original stone, there are problems such as cracks, black spots, damage, etc., so the purpose of manufacturing the illusion is to disperse the attention of the appraiser or cover up the defects. The methods are mostly ink, writing, tape or paper, mud, go The skin is not polished or the large piece is open.

Five, mosaic patch

Open a colorless rough stone and inlay a piece of jade with a good color to deceive or cover up the inferior part of the interior. When appraising, pay attention to whether there is any difference in the inlay or opening, and whether there is any adhesion mark.

Six, heart coloring

Use a jade stone with a colorless texture to dig a hole from the middle to a few millimeters of the surface and apply green material such as green paint. Use tin foil paper and then stick the mouth. This fake jade stone is similar in appearance to the natural one. And the color always gives people a feeling of shallow inside and deep. But in general, this color behaves like a piece of polished glass with a green back. Adhesion marks are also the main basis for identification.

Seven, skylight cap

Mostly inferior jade. After seeing the poor color difference after cutting, the opening is re-bonded. At the time of identification, attention should be paid to the presence or absence of gluing marks or changes in color and sand of each part. The change in color tone and the like of each part of the skin case was observed in the sunlight.

Eight, the hole to fill the hole

The internal situation of the original stone is unknown. In order to understand the internal situation, a small hole is drilled first. See the texture is poor, colorless or color difference; or remove the green and then fill the hole. Because of its small size, it is generally not easy to find.

Nine, forged weathering

Inferior jadeite or false shells for other reasons, in order to cover up their artificial marks, buried them in the soil, and placed corrosive substances such as acid or alkali around them. This allows the performance of the skin to resemble natural weathering.

X. Hollowing and deepening

For jadeite with dark green and poor transparency, the bottom or interior of the jade is hollowed out, which is intended to increase light transmittance and enhance transparency.
