When ordinary consumers buy jadeite, how do they know whether the jadeite they buy is true or not? This is a problem that almost all customers will encounter when buying jade. In this regard, some merchants will say: every piece of jade I sell is true, because every piece of jade has an appraisal certificate. The jade appraisal certificate is indeed an important basis to prove the authenticity of jade, which is equivalent to the ID card of jade jewelry. Because the jadeite appraisal certificate can prove the authenticity of jadeite, some unscrupulous traders often make fake jadeite appraisal certificates to deceive consumers, so it is particularly important to test the authenticity of jadeite appraisal certificates. Then, as a consumer, how to check the authenticity of the appraisal certificate? What are the inquiry methods of jadeite appraisal certificate? Lin, a senior jade appraiser, will introduce you to the relevant inquiry methods and precautions.

First, how to inquire about the jade appraisal certificate The purpose of inquiring about the jade appraisal certificate is to verify the authenticity of the certificate and prevent the rights and interests from being damaged due to false certificates. The certificate inquiry methods provided by most regular jade appraisal institutions mainly include the following:

1, website query At present, most formal and legal jade appraisal institutions have established their own websites to provide consumers with their own appraisal certificates. The address of the inquiry website will be marked in the eye-catching position of the certificate. Consumers can find the relevant data of the certificate on the website as long as they log on to the inquiry website and enter the number, weight, verification code and other parameters of the jade appraisal certificate according to the tips of the website. As shown in the following figure: In the process of website inquiry, the matters needing attention include: a. Input method: For example, the certificate number of some inspection stations contains English letters, so the English letters on the appraisal certificate are capitalized, so it is necessary to input capitalization when inquiring. B, picture problem: Some inspection stations can only provide certificate data query, no picture query, so consumers should carefully check whether the certificate data is consistent, including the weight of the object. On the website that provides picture inquiry, the picture displayed must be exactly the same as the picture on the certificate. Once the pictures are found to be inconsistent, it is necessary to doubt whether the pictures have been replaced by illegal vendors and further verify with the appraisal agency.

2. Telephone inquiry about the appraisal certificates issued by all jade appraisal institutions can directly dial the fixed telephone number on the certificate. And generally speaking, there is a special person to answer the phone and answer any questions about the certificate. Therefore, telephone inquiry is the most widely used and least restricted certificate inquiry method. Moreover, if consumers have some professional questions, they can also get good answers.

3. SMS inquiry Some jade appraisal institutions also provide SMS inquiry methods. The specific method is to edit the certificate number into a short message according to the prompt on the certificate and send it to the designated number. The query results are also sent back to the consumer's mobile phone via SMS. Some checkpoints of this service are free, and some checkpoints are charged.

4. QR code scanning query With the increasing scale of smart phones in society, there are more and more users of WeChat and Weibo. The information capacity of QR code is so large that it can contain the information of an authentication certificate, and its anti-counterfeiting ability is so strong that it is almost impossible to forge it. Therefore, by scanning the QR code on the authentication certificate on the mobile phone, you can see all the information of the authentication certificate on the mobile phone, and compare it with the certificate in your hand to verify the authenticity. This very convenient and free inquiry method can only be provided by the jade appraisal certificate of Yunnan Jewelry and Jade Quality Supervision and Inspection Institute.

Second, how to look at the contents of the jade appraisal certificate. The contents of the jade appraisal certificate include: the name and qualification of the appraisal institution, the type of inspection standard followed, the inquiry method, the inspector, the auditor, the approver and the date. The inspection parameters generally include the following contents:

1. Inspection conclusion: jade (if it is natural, it will be written as "jade" or "jade pendant"; If it is not natural, it is written as "jade (treated)", "bleached filled jade" and "jade (bleached filled)");

2. Total mass: **g (refers to the weight of this jade at the time of identification, in grams, generally accurate to two to three decimal places);

3. Shape: refers to the appearance of jadeite products, such as bracelets or pendants.

4. Color: Jade has many colors and tones, and the color or floating color should be indicated;

5. Refractive index: 1.66 (spot measurement) (this is the unique refractive index of jadeite itself which is different from other gems);

6. Density: 3.33 (specific gravity is also a feature that distinguishes it from other gems);

7. Gloss: glass luster (the surface luster of treated jadeite will be weakened to weak glass luster or waxy luster due to pickling);

8. luminosity: heterogeneous aggregate (jadeite is a micro-mineral aggregate);

9. Fluorescence: no fluorescence (some B and B+C jadeites will have abnormal fluorescence reaction under ultraviolet lamp after glue injection);

10, absorption spectrum: 437nm absorption line (this is the unique absorption spectrum of jadeite); 1

1, amplification detection: fiber interwoven structure or granular fiber structure (this is the unique structure of jadeite); As the certificate style of each jade appraisal institution is different, the contents listed above are only possible. If there are only some of the contents listed above on the jade appraisal certificate, it does not mean that the certificate has no legal effect.

Three. Matters needing attention in inquiring jadeite appraisal certificate

1. Pay attention to distinguish whether the query result is true or not. When you get a jade appraisal certificate, you should first check the authenticity of some background contents on the appraisal certificate. These background contents are neglected blind spots in the eyes of unscrupulous merchants who forge certificates because of their strong professionalism, but it is often these blind spots that expose fake jade appraisal certificates. The following is an endless example of fraud: A. It is mentioned in the introduction that measurement certification and quality approval have been passed, so only two signs of "CMA" measurement certification and "CAL" quality approval will appear in the certification mark of the certificate. However, the certification marks appearing on the actual certificate are "CMA" (measurement certification) and "CNAS" (laboratory accreditation by China National Accreditation Committee for Conformity Assessment). That shows that there are serious errors in the certification mark of the certificate and the background introduction of the testing station. It is absolutely impossible for a formal jade appraisal institution to make such a serious and incredible mistake. B. The query of laboratory number under CNAS logo shows: Guangdong Jewelry, Jade and Precious Metals Testing Center. Every standardized jadeite appraisal institution will issue an accreditation certificate after it has passed the laboratory accreditation of China National Accreditation Committee for Conformity Assessment. On this certificate, there will be the full name of the accreditation body and the number of the accreditation certificate. This information can be found on the official website of China National Accreditation Committee for Conformity Assessment. Therefore, according to the query results, the number of this CNAS logo does not match the appraisal institution written on this appraisal certificate, which is commonly called deck. C. The ringtone voice of the supervision telephone prompts that this number belongs to Ruili Jewelry Testing Station of Dehong Quality and Technical Supervision Bureau. At present, the CRBT voice prompt of domestic fixed telephone involves the company or company name, and it needs to apply for business license or company certificate. Therefore, when dialing the fixed telephone number written on the certificate, a CRBT voice prompt from another company appears, which only shows that the telephone number on this certificate is that of another company.

2. Data easily misunderstood in the certificate A. Quality: The "quality" on the jade appraisal certificate actually refers to "weight", not the quality of jade. I have learned in physics class in middle school that the exact expression of the actual weight of each object is the word "quality". Only in daily life, everyone is used to "weight"; B, when the jadeite has been strung with rope or inlaid with metal during identification, isn't the "density" written as 3.33g/cm? Yes; C. Some inspection items that have not been tested or evaluated will be indicated by "* * * * *". But in the mouth of some businesses, this means five-star quality, which is wrong.

3. How to see whether the certificate is consistent with the real thing A. Look at the picture-compare the real thing with the picture on the appraisal certificate. There may be differences in color and hue, but the basic external characteristics of jadeite can still be compared. The basic external features of jadeite jade include: the shape of bracelet (round, flat or wide-edged), the carving pattern of pendant, the distribution position and shape of color, etc. B, according to the quality-the quality on the jade appraisal certificate will generally be at least accurate to two decimal places. The quality of jadeite should be similar to the data in the certificate (the error of 0.0 1-0.05g is normal). Through the above two steps, you can basically determine whether the certificate is consistent with the real thing. If any inconsistency is found, you need to call the jade appraisal institution to verify the specific reasons.

Legal basis:

Article 29 of the Notary Law of People's Republic of China (PRC) * * * If the notarization institution needs to verify the matters applied for notarization and the certification materials provided by the parties concerned in accordance with the relevant provisions or has doubts, it shall verify them, and the relevant units or individuals shall cooperate according to law.

Derivative problem:

What are the procedures for notarization?

1, application.

That is, the parties submit a notarization request to the notary office. When applying for notarization, the parties concerned shall personally submit it to the notary office and fill out the notarization application form. If you entrust others to handle it on your behalf, you must submit a written power of attorney to the notary office, which shall specify the agency matters, authority and time limit, and be signed and sealed by the client. However, when handling notarization, declaration, adoption of children, will, signature and seal, etc. No one may entrust others to act as agents. If the party concerned has real difficulties due to illness or other reasons and cannot go to the notary office for notarization in person, the notary can go to the place where the party concerned is located. State organs, enterprises, institutions, people's organizations and other legal person organizations shall apply for notarization on their behalf by their legal representatives or agents holding the power of attorney of the legal representatives, and the agents shall submit the agency certificates.
