Identification of jadeite bracelet
Identify the authenticity of jade bracelets through quality inspection stations.
Without the help of laboratory instruments, it is difficult for ordinary consumers to make an accurate judgment on the authenticity of jade bracelets and their real materials only by naked eyes or simple methods. In order to get the most reliable and accurate judgment result, the simplest and most convenient way is to ask the merchant for the jade bracelet appraisal certificate or get it to the local quality inspection station for appraisal. Different inspection stations charge different fees, generally ranging from 20-200 yuan. The appraisal certificate of the national authority has a high accuracy in jade appraisal. It should be said that there are few cases of lost goods. Even if there is a problem and it brings losses to consumers, you can pursue compensation, because today's jewelry appraisers are responsible for the appraisal results, just like certified public accountants.
It is the simplest and most convenient way to ask the merchant to issue a jade bracelet appraisal certificate when purchasing, and it is also a written certificate to guarantee consumers. The jade bracelet appraisal certificate is rarely fake, as long as it is a certificate that can be queried online, it is a real certificate. On the jade bracelet appraisal certificate, the address, telephone number, website and other information of the appraisal institution are written, which can be inquired by calling or surfing the Internet. If you can find it, it is a real jade bracelet.

Identify the authenticity of the jade bracelet by yourself.
If you want to identify jade bracelets, you can judge them by some common sense besides attending professional training courses on jade bracelet identification. These common senses sum up to three points:
1) There is no pie in the sky. The jade bracelet that is too cheap and beautiful is 100% fake.
2) There is no perfect jade in the world, and there are no perfect people. Perfect things can almost be judged as fakes.
3) Ancestral jade bracelets can almost be judged as jade or fake jade. In modern China, the people were very poor, most of them lived in a farming society and were generally poor. Wealthy people rarely pass on the precious jade bracelets handed down from their ancestors to their descendants.
One of the Identification Methods of Emerald Bracelets —— See the Transparency of Emerald Bracelets
According to the current jade market, even an ordinary ice jade bracelet costs more than 10,000 yuan. If it is an ice flower bracelet, the price should be at least 65438+ 10,000 yuan. So if you see a transparent jade bracelet with a price below 10000 yuan, it is probably a fake jade bracelet! You can compare your bracelets. If the bracelet is very transparent, but you only spend a few hundred dollars, even1-2,000 yuan, it can basically be judged as a fake, and naturally it won't drop the pie.
The Second Method of Identifying Jade Bracelets —— Looking at the Defects of Jade Bracelets
Generally, the jade bracelet of A goods will have some impurities more or less. If the interior is too clean, the price must be quite expensive! The price of jade bracelets can also reflect many problems at some time, so be careful of jade bracelets with a few hundred yuan and pure texture. Generally speaking, the price of jade bracelets is relatively high.
Natural jadeite is bound to have flaws, and flaws are the basis for distinguishing between true and false.
Fake jade bracelets must be flawless, green and transparent, and cheap. Only if they are good-looking, can they cheat you.
The third way to identify jade bracelets-look at the color of jade bracelets
If a jade bracelet is all green and the price is only a few hundred or several thousand yuan, it can basically be concluded that it is a fake jade bracelet. Even if the jade bracelet is all green impurities and opaque, the price should be at least 50 thousand yuan. Jade bracelets are rich in color, and there are many kinds of jade bracelets. When buying, everyone must keep their eyes open and don't be confused by superficial phenomena.
Identification method of misspelled jade bracelet
Some identification methods of jade bracelets, such as fire, knife carving, tapping and listening, dripping water, etc. It has been circulated on the internet, which is not desirable. Let's analyze the hazards of these identification methods.
1) burn with fire
Some people put forward a method to identify jade bracelets, saying that jade was burned with a lighter. If it is generally cold after burning, it means that jade is real, and it is hot after burning, which means that the original jade stone is fake. Such a jade appraisal method is not only very wrong, but also very harmful to real jade. Burning jadeite, whether true or false, will be hot, and jadeite will be burnt out, so such a jadeite identification method is really not desirable.
2) Wrap your hair and burn it.
There is an identification method of jade bracelets, that is, Myanmar-Zhuhai jade is tightly wound with hair for a week, and then the hair is baked with a lighter. If the hair is baked continuously, it means that the jade is real, and if it is baked off, it means that the jade is fake. Such a method is also a fake method. It is said that someone has done an experiment for this. The hair is tightly wound on a plastic ballpoint pen and baked with a lighter, which will last for a short time.
3) Drip method.
For example, some people say that if a drop of water falls on jade, it is true that it does not disperse but condenses together. Is this jade identification method reliable? In fact, this method is a fake method that you can think of with your toes. Because whether the water drops will scatter when falling on the jade is related to factors such as the acceleration of gravity and the smoothness of the jade surface, it has nothing to do with the authenticity of the jade.
4) Carve with a knife.
Jadeite is jadeite with high hardness. It is impossible for ordinary knives to carve jadeite and leave scratches on its surface. This method has certain scientific truth, but it is not desirable. First of all, this method is a destructive testing method. If you have another jade in your hand, scratching with a knife may leave scratches and cause damage. Secondly, there are many stones with higher hardness than knives. Pick up a stone by the river and the knife won't move. Therefore, this method cannot be used to identify the authenticity of jade bracelets.
