It may not be true. Certificates or real jadeites can be forged. Some people take the real jade for identification and pass it off as fake jade that looks almost the same.
Not necessarily. Emerald with certificate is not necessarily true. Although when buying jade, in order to have a sense of security and convince consumers, merchants are generally required to issue authoritative jade appraisal certificates.
Your question, the certificates that can be found on the regular network are basically true. The problem may be the goods, not the certificates. It may be for you, not the goods on the certificate. This situation does exist. If you don't feel at ease, you can spend tens of dollars to go to an appraisal agency for appraisal. Fake ones can go to business theory.
Hello, I'm glad to explain to you that jewelry with appraisal certificate is not necessarily true, because the certificate can be fake.
Although some things come from a piece of raw material and look similar in appearance, jade ornaments are not exactly the same. One thing with a certificate can't prove the quality of the whole batch of things.
Generally, what can be found on the website of the National Appraisal Center is a piece of jade, which is a natural jade product, but it does not mean it is valuable. Similar to the picture, this type is also an emerald bracelet, but the color difference is only about 200-400. You can compare and refer to it.
The weight difference between the bracelet and the certificate is11g. I wonder if it's true.
This is normal. There will be some errors in the processing of products, and at the same time, manufacturers will increase the amount to prevent the possibility of product wear. The error of 0.0 1 is very small.
The real test certificate has the steel seal of the test center. If the inspection certificate received does not have the steel seal of the inspection center, it may be fake. Other identification methods of silver bracelet certificate: look at the certificate seal: the test certificate has the test center seal.
There is an error in the weight on the jade certificate. For the jade bracelet shown in the picture, there is no problem! The reason why the weights of the three times are different is that when the landlord looks carefully, they are all in the second place after the decimal point, which is caused by the lack of weighing equipment and accuracy. Weighing with a high-precision jewelry scale, the value does not fluctuate.
I bought a piece of jade, and the certificate really has a difference of 0.35g between its own weight and the certificate weight. Is it normal?
1, not normal. Generally, the weight is simple, and the second place after the decimal point does not exist. Besides, your things are so different.
2, the difference is so much, it is likely that the certificate is fake. Usually at least the weight can't be wrong.
3. Water: High transparency, bright water permeability means good water head. Generally, good plants have good heads. Poor transparency, opacity is suitable for dry head. Defect: no crack and no defect is the top grade. With black, dirty and cracked vitamins times. Few jadeites produced in nature are perfect. Technology: exquisite design, fine workmanship and careful polishing are better.
The weight of jadeite differs from that shown on the certificate by 0.35g, that is, it is 0.35g more. ...
1, water: high transparency, bright water permeability means good water head. Generally, good plants have good heads. Poor transparency, opacity is suitable for dry head. Defect: no crack and no defect is the top grade. With black, dirty and cracked vitamins times. Few jadeites produced in nature are perfect. Technology: exquisite design, fine workmanship and careful polishing are better. On the contrary, it is second.
2. Under normal circumstances, there will be errors in electronic weighing of different testing institutions. Some institutions are lazy and often no one calibrates them. In this case, the quality error of different institutions will be 0.XXg.
3, abnormal, the general weight is simply omitted, and the second most precious thing after the decimal point is generally not omitted, not to mention your things are so much worse.
4. Landlord, there is nothing inconsistent with the certificate by visual inspection. Out of rigor, there is an objective way to check. Weigh the bracelet with an accurate jewelry scale. If the actual gram weight of the bracelet is equal to 779 grams marked on the certificate, the certificate is in conformity with the real thing.
I bought a bracelet in the mall, but the certificate and the real thing are different in appearance and weight. Who is it? ...
1, depending on the error, different electronic scales will have errors, and almost nothing will happen. There is also whether the jadeite rope or accessories are the same as now when the L/C is opened, which also affects the weight.
Secondly, it depends on whether the electronic scale used by the store is accurate. According to the regulations, all gold and silver jewelry distribution points should be equipped with high-precision electronic balances accurate to three decimal places, and stamped with strong inspection certificates; Thirdly, consumers should weigh gold and silver products on qualified electronic scales in the store to avoid losses caused by short weight and short weight.
If you think that the weight on the jade certificate does not match the actual weight, you can consult the seller to solve it. As for the size and weight of this jade bracelet, it needs to be considered comprehensively according to personal preferences, wrist size and style.
