1, jadeite is gray, which may be due to the impurity of chromonic metal ions in jadeite, such as chromium forming green, iron oxide forming yellow and so on. The higher the content of chromogenic metal ions, the deeper the color, and the larger the color distribution area of jadeite. Emerald is gray, which may also be caused by improper maintenance.

2. It is normal that jadeite has different effects under different light sources due to the refractive index. If jadeite can maintain an effect under different light sources, it is not normal. .

3, it doesn't matter if it changes color under light. Just because everything is different in color under light and natural light doesn't mean it's a fake.

4, the reason for whitening: whitening is a poor foundation, it is naturally formed and cannot be changed, but as long as it is natural, for the efficacy of the human body, the minerals with poor foundation are more abundant. Long-term wear will make jade color better, smoother and more transparent.

It is normal that the jade bracelet will emit white light under the light.

Why do jade bracelets glow purple under fluorescent lights?

The fluorescence reaction of jadeite bracelet under violet light indicates that it may be grade B jadeite, which is a product of post-artificial treatment using natural jadeite raw stone. Its essence is jadeite raw material, just because the texture is not good enough, and some impurities are more, so merchants beautify it for sale.

Generally speaking, if it is natural jade, it will not change with purple light, which is the primary color, because natural jade is unresponsive to ultraviolet light.

Hello, the purple light of the jade bracelet in the light shows that it is fake. Ultraviolet rays in sunlight will react with fluorescent substances and turn them purple.

The jadeite bracelet is irradiated with ultraviolet rays, and the whole body is blue and purple, indicating that it is fake jadeite. Natural stone will not have fluorescence reaction, and natural jadeite will not shine under ultraviolet light. If it is B goods or B+C goods, there will be blue and white fluorescence. B the filler of jadeite, epoxy resin, will fluoresce under fluorescent lamp.

You have to shine this with an ultraviolet light, the kind that checks money. If there is an obvious blue-purple fluorescence reaction, it is not jade A, it is pickled. I hope it helps you.

Hello, if you shine anything with purple light, it will show purple. However, when jade B is filled with epoxy resin, it will have obvious fluorescence performance. Note that it is really obvious fluorescence, not purple. So purple is normal and fluorescence is abnormal. Good luck.

Emerald bracelets are sometimes bright and sometimes not so bright.

Because there is wax in polishing. This happens when the wax recedes after you put it on, or when you touch something greasy. Do you have a certificate? It may also be treated jadeite. It is suggested that the material object shall prevail. See the specific goods for reference only.

The first possibility is the unfortunate purchase of a processed jade bracelet. These treated jade bracelets are likely to change color and fade when worn for a long time, and will turn yellow and black when viewed from the outside.

Generally speaking, jade bracelets are getting lighter and lighter for two reasons. First, due to long-term wear and tear, the wax protective layer on the surface of the jade bracelet was wiped off after a long period of friction, and the jade surface also lost its protective layer. As time goes on, a layer of dirt will form on the surface of jadeite, which will affect the color of jadeite.

Hello, natural A jade is more oily and shiny. Hand sanitizer in daily life can't have any destructive influence on natural jadeite. After all, even soft leather can't hurt, and hard gems are more difficult to hurt.

In this environment, the water of jadeite will not be lost, but will be replenished, making jadeite look watery. Wipe with soft silk. You can always wipe the jade bracelet with soft silk cloth to make it brighter.

Maybe it caused it. I feel a layer of oil, which may be caused by some um oil secreted by your body or sweating. Bracelet, also known as "hairpin", "bracelet" and "arm ring", is a ring-shaped ornament worn on the wrist.

Why is jadeite dull?

There are many Cui friends who like jade, but in daily life, many Cui friends are not particularly particular about their wearing habits and do not pay attention to maintenance, which may easily lead to friction between jade and other substances. Over time, they will find that jade seems to be "plain". This "blandness" can be polished by a polishing machine, so don't worry.

Moreover, the refractive index of jade in the sun makes its permeability in human eyes not so high, and the fluorescence, glue and double eyelids are not so obvious, so the jade bracelet in the sun is not so bright.

The jadeite bracelet has been worn for a long time, which leads to friction marks on the surface of the jade body and becomes dull. It just needs to be polished again and it will be brand new. 2. The jadeite bracelet, which is dull due to dirt adhesion, is soaked in concentrated rice washing water for several hours, then washed with a soft brush, and repeated several times until it is taken out.

Jade jade has lost its luster after being left for a long time. There are two solutions: due to dust, human body fat adheres to the surface of the jade body, which is not worn for a long time and is not well kept, resulting in oxidation reaction on the surface of the jade body and dull luster.

It may be caused by improper polishing and belongs to natural jadeite. If the jade bracelet is not polished properly, the color matching of the jade safety buckle will cause insufficient surface finish, which is certain. Jade that people wear for a long time will be "more transparent, brighter and greener."

Why do jade bracelets look so rough and ugly in the sun ~ ~ but in cloudy or sunless nature? ...

1, the difference between sunlight and our fluorescent lamp is the influence of ultraviolet spectrum. Generally, the ultraviolet spectrum of jadeite jade does not show fluorescence, which is a feature.

This bracelet is very good. If you look at the water head in cloudy or ordinary light, it proves that you have bought a good product, but it is only a visual difference. "No light (sunshine, daytime), don't buy, don't look at jade (jade)" is a jargon, which means that the water head will be more obvious and the effect will be better when it is sunny during the day.

Sunlight is the magic mirror of jade. The cotton wool on the surface and inside of jadeite will be particularly obvious in the sun, and the refractive index of jadeite in the sun makes its transparency in human eyes not so high. Those fluorescent, rubber and double eyelids are not so obvious, so the jade bracelet in the sun is not so bright.

4. It can't be proved. The variety and quality of jadeite can't be judged only by observing in light or sunlight, because the color and transparency of jadeite are influenced by many factors.

5. This kind of jade bracelet is translucent, the background color is light wax gray, and some areas are light oil blue. Jade is made of crystal, which is transparent and easy to refract and diffuse light, so it will produce different color visual effects under different light intensities and different observation angles.

Why does my jade bracelet look particularly transparent (opaque) in the dark or under the lamp? Also went in. ...

1, the difference between sunlight and our fluorescent lamp is the influence of ultraviolet spectrum. Generally, the ultraviolet spectrum of jadeite jade does not show fluorescence, which is a feature.

"No light (sunshine, daytime), don't buy, don't look at jade (jade)" is a jargon, which means that the water head will be more obvious and the effect will be better in the daytime sunshine.

3. The disadvantage of observing jadeite under the light is that the color of jadeite will look more beautiful under the light, which will improve the grade of jadeite. Specifically, light can improve the luster and transparency of jadeite and make some common colors look lovely.

4, jade material reasons, bracelets should be polished with wax, wax will improve the gloss of jade, will not affect its transparency. Wear it for a long time, the wax will gradually evaporate, so the bracelet looks transparent.
