Characteristics of fake jade bracelets

The fake jade bracelet is characterized by bright colors, corrosion marks and cracks inside.

1, brightly colored

The color of fake jadeite is usually too bright, dull and yellow, and there is no color root. In a word, the contrast between color and background is too strong and unnatural.

2, there are traces of corrosion

Fake jade bracelets are usually acid-washed, so there will be many traces of corrosion on the surface, which may not be visible to the naked eye, but the luster can be revealed. In the current counterfeiting process, in order to cover up these pits, resin is often used to repair these pits.

3. There are cracks in it

In the case of light transmission, the tensile cracks interwoven vertically and horizontally in the fake jade can be clearly seen with a magnifying glass, the grains are dislocated, the directionality is lost, and the transparency is sometimes bad and uneven.

Fake method of jadeite original stone

1. Fake chip opening: make a small hole on the colorless low-grade gambling stone with poor water head, and paste a high-quality chip to make it sub-optimal. When identifying, we should carefully check the adhesion marks around the opening (door), the influence of gap shape and temperature difference on it.

2. Fake leather shell: Glue inferior materials, waste stones and fakes with high-quality jade leather shells, and then bury them in the soil soaked in acid and alkali to make them look like "genuine leather" to cover up artificial traces. First, clean it with water, check every point and every surface of the shell, and don't let go of tiny holes, cracks and holes, and compare the changes of color and particle size.

3. pseudo color: Coloring and dyeing turn colorless and light-colored materials into bright turquoise, as well as waxing, painting and deep mud. During identification, the color of enamel turns red with a color filter, and the color distribution changes with a magnifying glass. The artificial coloring in the tiny cracks is heavier, and the other parts are lighter or colorless. Before observing the change, wash and heat it slightly.

4. False heart: Dig the heart to take out a part of high-grade jadeite, leave the high-grade jadeite on the skin, and then inject lead and other substances to seal the incision. If the weight is too heavy or too light, it may be fake. For the outer skin, you can use a chain and a knife to scratch whether there are uncertain soft objects and look for signs of sticking.
