Excuse me, is it fake that jadeite is blue with 365 purple light?
The method of identifying jadeite by purple light is as follows: If it is genuine jadeite, then under the irradiation of purple light, we will find that jadeite actually does not emit light, or a small number of jadeite will emit a small amount of light, but the light emitted is punctate.
Ultraviolet fluorescent lamp: purple light can be said to be a good helper to identify jadeite. Putting jadeite under purple light, natural jadeite has no fluorescence reaction. If it is dyed jadeite, it will have a fluorescent reaction. This method is especially effective for jadeite to dye purple, and purple jadeite has a strong fluorescence reaction under purple light.
Purple light can identify the filled jadeite, that is, the jadeite that can identify B goods. The jadeite with fluorescence reaction under purple light must be treated; Without fluorescence reaction, it can't be proved to be real jade. Ultraviolet lamp is a sharp weapon to detect jade counterfeiting, but it is impossible to detect jade counterfeiting from other materials.
When you look at jadeite with purple light, you need to observe jadeite under purple light. Generally, fake jadeite will have fluorescence reaction under purple light, while natural jadeite will not have fluorescence reaction under purple light.

When we irradiate with violet light, if jadeite has fluorescence reaction, it must be fake jadeite, because this part of jadeite is actually artificially dyed in the later stage. This jadeite contains a lot of epoxy resin, which will fluoresce under the irradiation of violet light.
To identify the authenticity of jadeite with purple light, we should first wash it, then find a dark place and observe it after being irradiated with purple light. True jadeite is one that does not glow under purple light or only emits a little fluorescence. Violet light emits strong fluorescence, and the overall brightness is fake jade.
Is it false that the uneven surface of the purple-illuminated jade pendant has blue spots?
Jade bracelets, under fluorescent lamps, have a little fluorescence, which is not the standard for judging authenticity. I suggest you take some photos and upload them in natural light, so that I can give you detailed comments and evaluations.
Generally speaking, yes, but they are all purple. If it's just one or two points in the carving, it may be that polishing powder is left on it. If it is really unclear, it is recommended to spend more than ten yuan to identify the agency.
Mida bracelet with blue light and purple light is fake. The real Mida bracelet jade will not change color under the purple light, and it is still the original color. The fake jade bracelet will appear blue and purple under purple light.
The jade bracelet I bought is light blue in some places under the light. Is it fake?
1, look at the picture, the probability is A goods (that is, true). Didn't you have a certificate when you bought it? Send it up if you have it. It's not surprising that jadeite has various colors, and it's normal that different light will show different color changes.
2. Using ultraviolet rays to irradiate the jade bracelet, the whole body is blue and purple, indicating that it is fake jade. 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.
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.
4. This is a common way of counterfeiting in recent years. The jade bracelet itself is a real natural jade. However, it is an entry-level jade bracelet with thick seed material, thick cotton, short water head and plain color. Then apply dyeing and polishing powder to make bright colors. Therefore, this will happen when ultraviolet light is used.
5. The seed is thick, the cotton is thick, the water head is short, the stripes are slightly thin, and the waxy white background is slightly gray with a hint of lavender. The whole jade bracelet belongs to the middle and low grade. If there are no destructive defects such as cracks, the market price of jadeite is around 1200 ~ 1500 yuan.
6. Of course, this phenomenon will only appear in ice seeds or glass jadeite. Natural jadeite cannot be perfect. Some cracks exist in the raw ore, and some are caused by processing. For jade bracelets, cracks are very taboo, especially transverse cracks, which may cause the bracelet to break at any time.
I bought a jade pendant in the same store, and found that it was fluorescent under purple light. Could it be fake?
1. In this case, the probability of counterfeit goods is very high. Be very careful, don't be fooled.
2. Under the violet light, some artificially treated jadeites will fluoresce, indicating that these jadeites have fluorescent agent residues, and jadeites with fluorescent reaction are not natural jadeites. Purple fluorescent jadeite is not necessarily a fake, but it can be guaranteed that it is not a good product.
3. It can't be completely confirmed that jadeite purple light has a fluorescence reaction, because jadeite will use polishing powder in the polishing process, and the residue of polishing powder will have a fluorescence reaction, so it can only be said that jadeite purple light has a fluorescence reaction.
4. If it is genuine jadeite, then under the irradiation of purple light, we will find that jadeite is actually non-luminous, or a small number of jadeite will emit a small amount of light, but the light emitted is punctate. If inferior jadeite or jadeite is stirred, the emitted light beam is point fluorescence.
What are the five advantages of acrylic lamp?
Advantages a, excellent weather resistance, strong adaptability to the environment, even if it is exposed to the sun for a long time, the performance will not change, and the aging resistance is good, so it can be used outdoors with peace of mind. B, non-toxic, even if it is in contact with people for a long time, the gas produced during combustion will not produce toxic gas.
Advantages of acrylic lamp: strong color durability. High gloss appearance, bright color, no discoloration or fading within 58 years. Strong light transmission. Outdoor advertising industry, good light transmission, uniform and soft brightness at night, overall light, shining lines, soft light. The light source has a built-in light source.
Advantages of acrylic chandelier color: the color can last. The appearance is bright and gorgeous, and it will not fade and change color for five to eight years. Light transmission: the light emitted is very bright. In the outdoor advertising industry, it has a strong light transmission performance and a symmetrical and mild brightness at night, which belongs to the whole luminescence.
Strong color persistence. Acrylic has high gloss and bright color, which lasts for 5-8 years, in other words, it will not change color or fade within 5-8 years. Strong light transmission.
Advantages of acrylic lamp-Shenzhen Jinlipin has strong color durability. The appearance has high gloss and bright color, and will not change color or fade in 5-8 years. Strong light transmission.
