1, due to external pollution. Some jadeites are getting whiter and whiter, which is caused by external pollution. At this time, it is suggested to soak the jade in warm water first, brush it with a brush after 30 minutes, and then soak it in boiling water at about 90℃ for three times until the water soaked in the jade is completely cooled.

2. Structure: During the formation of jadeite, the internal wafers are distorted or dislocated, resulting in uneven crystal arrangement; Density, the smaller the density of jade bracelet, the larger the structural gap, and the more white cotton wool will naturally be; Impurities, the external impurities absorbed by jadeite during the formation process, will be transformed into white cotton wool, which will affect the texture.

3. Some jadeites, such as Huang Longyu and Dangerous Jadeite, will dehydrate after a period of time, because the jade species are too tender.

4. After being worn for a period of time, jadeite B bracelets, jadeite C bracelets, jadeite B+C bracelets and other dyed jadeite bracelets will fade due to environmental changes and return to the state before dyeing. However, the filled epoxy resin or wax, because of aging, makes the surface of the treated jade bracelet lose its luster and its transparency decreases.

After the jade fell to the ground several times, there were white marks. How to fix it?

1. The jade pendant is broken. If the fracture of jade is flat, you can ask the master to glue it with special jewelry. If the fracture of the jade is flat, you can ask the master to glue it with special jewelry to restore the original appearance of the jade.

2. If the jade pendant is broken, it can be repaired by waxing, tracing gold and inlaying. If the jade fracture is relatively flat, you can ask the master to glue it with special jewelry.

3. If the jadeite falling crack is not serious, only some cracks appear or break in two, in this case, the broken parts can be connected by gold or silver cladding at the place where the jadeite falls crack.

What are the reasons for the different colors of jadeite?

1. In fact, the color of jadeite is mainly caused by isomorphic substitution of trace elements such as chromium, titanium, iron and manganese. The higher the content, the darker the color, and the less the content, the lighter the color. Color-causing elements in jadeite are often unevenly distributed, so local colors may be thick or light, or thick or scattered.

2. These colors are formed by the iron oxide released by the weathering of iron-bearing minerals in jadeite, which is leached by colloid and infiltrated into the gaps or micro-cracks between jadeite crystal particles. These colors are not the inherent colors of jadeite crystals. These colors are unstable and may be completely dissolved by soaking in strong acid, thus fading jadeite.

In fact, the color of jadeite depends on the elements that make up the mineral and what type it belongs to. And it will show different colors with different element contents, commonly known as primary colors.

4. It is caused by the infiltration of organic carbon and metal components in the later period. Yellow and brown jadeite: It is colored because it contains many secondary minerals such as goethite and limonite. Maroon jadeite: Hematite is dehydrated from minerals containing iron oxides.

The word Fei stands for two colors, red and yellow. Both red and yellow are due to the fact that iron enters the jadeite body during the formation of jadeite, resulting in red and yellow.

What's wrong with the color of the finished product processed from jadeite original stone chips?

1, polishing. The original jadeite stone is only made in appearance, with rough surface, impurities and impure color. After that, it will be polished and polished into a finished product, so that the color of jadeite can be pure, which will lead to the difference between the blank and the finished product.

2. The color elements in jadeite are often unevenly distributed, so local colors may be thick or light, or thick or scattered. Emerald

3. The color of the window is not consistent with the cut color. It is very likely that you bought a fake jade stone. As you can see from the above picture.

In fact, the color of jadeite depends on the elements that make up the mineral and what type it belongs to. And it will show different colors with different element contents, commonly known as primary colors.

First of all, the color of jadeite is different under different light. Secondly, the certification body only verifies whether the jade is natural. He gave a general description of his photos and didn't pay attention to the color. Therefore, it is normal and common that the color described in the certificate is inconsistent with the color of the object you see.

6. Some dirt and dust in life will be adsorbed on the surface of the jade bracelet. Some tiny dirt will even penetrate into the jade surface through tiny cracks on the jade surface. As time goes on, a layer of dirt will form on the surface of jadeite, which will affect the color of jadeite. So the jade bracelet doesn't look as bright as before.

Is it normal that the front and back colors of green jadeite are different?

1. Due to different mineral elements, jadeite has different colors, such as white (colorless), green, purple, black, red and yellow. There are many chromogenic factors in jadeite, and different colors are composed of different chromogenic ions.

2. normal. There are up to 3 colors. There are two kinds of jade, soft and hard. Usually jade refers to nephrite, and jadeite also has a popular name-jadeite. Nephrite is a kind of hydrous calcium magnesium silicate with hardness less than 5, excellent toughness, translucent to opaque, and fibrous crystal aggregate.

3. The reason why half of the color under the jade Buddha lamp is different: the color of jade is caused by chromium.

What do you think of the defects of jadeite?

1. Cracks and cracks are basically recognized in the jade industry; Emerald is not a flaw; Miscellaneous tendons, stone lines, stone flowers, mottled colors, stains, etc. If it is deep enough to affect the beauty of the original, it is considered a defect; If it is so shallow that it has no obvious influence on the beauty of the original, it is not considered a defect.

2. What do you think of the defects of jadeite? You can touch the surface with your fingernails. If there is obvious jumping feeling, it is a crack. Dirty color. Generally speaking, the color of jade conflicts. More suddenly, the dirty color is usually black, gray or yellow spots.

3. Moss: The moss of jadeite refers to black or dark gray stripes or patches visible to the naked eye on the surface or inside of jadeite. The moss of jadeite varies in shape and size, with spots and stripes. Because the color is ugly and abrupt, it is called the "moss" of jade, which is a big flaw and should not be confused with the floating flowers of jade.

It is not bad jade that jade contains white cotton. It depends on the size and particle size of white cotton contained in jadeite. The white cotton particles that usually appear in waxy jadeite are slightly coarse and look like small white particle inclusions to the naked eye. The high density of white cotton will affect the quality of jadeite itself.
