What should be done to verify the authenticity of the appraisal items?

when ordinary consumers buy jadeite, how can they know whether the jadeite they buy is real or fake? This is a problem that almost all customers will encounter when buying jade. In this regard, some merchants will say: Every jadeite I sell is true, because every jadeite has an appraisal certificate. Jade identification 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 check 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 Qingchun, a senior jade appraiser, will introduce you to the relevant inquiry methods and precautions.

1. How to inquire about the jadeite appraisal certificate The purpose of inquiring about the jadeite 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 formal jade appraisal institutions are mainly as follows:

1. Website inquiry At present, most formal and legal jade appraisal institutions have set up their own websites to provide consumers with the inquiry of their 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 of the jade identification certificate and other parameters such as weight or verification code 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, some certificate numbers of inspection stations contain English letters, so the English letters are capitalized on the appraisal certificate, so it is necessary to input capitalization when inquiring. B, picture problem: some inspection stations can only provide certificate data query, and there is 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 pictures displayed must be completely consistent with the pictures on the certificate. Once the pictures are found to be inconsistent, it is necessary to doubt whether the pictures have been replaced by unscrupulous vendors and further verify with the appraisal agency.

2. To inquire about the appraisal certificates issued by all jade appraisal institutions by telephone, you 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 jadeite appraisal institutions also provide SMS inquiry. 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 specified number. The query results are also sent back to consumers' mobile phones by SMS. Some inspection stations of this service are free, and some inspection stations are charged.

4. QR code scanning query As the scale of smart phones is getting larger and larger in society, there are more and more users of WeChat and Weibo, and the information capacity of QR code is large enough to contain the information of an appraisal certificate, and its anti-counterfeiting ability is very strong, so it is almost impossible to forge it. Therefore, by scanning the QR code on the identification certificate on the mobile phone, you can see all the information of the identification 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.

2. How to read the contents of the jade appraisal certificate? The contents of a 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, and the inspection parameters generally include the following contents:

1. Inspection conclusion: Jade (natural) is written as "jade" or "jade pendant", while unnatural.

2. Total mass: ***g (refers to the weight of this jadeite when it is identified, in grams, usually accurate to two to three decimal places);

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

4. Color: There are many colors and tones of jadeite, so the color or floating color should be indicated;

5. refractive index: 1.66 (spot measurement) (this is the unique refractive index of jadeite itself that distinguishes it from other gemstones);

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

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 jadeites of B and B+C will have abnormal fluorescence reaction under ultraviolet lamp after glue injection);

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

1. Magnification detection: fiber interwoven structure or granular fiber structure (this is a unique structure of jadeite); As the certificate styles of each jadeite appraisal institution are 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.

3. Matters needing attention in inquiring about the jade appraisal certificate

1. Pay attention to distinguish that the inquired result is true. When you get a jade appraisal certificate, you should first check the authenticity of some background contents on the appraisal certificate. Because of their strong professionalism, these background contents belong to the blind spots that are ignored in the eyes of unscrupulous merchants who forge certificates, but it is often these blind spots that expose the fake jade appraisal certificate. The following is an endless list of fraudulent practices: A. It is mentioned in the introduction that measurement certification and quality examination and approval have been passed, so only two signs of "CMA" measurement certification and "CAL" quality examination and 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 means there is a serious mistake in the certification mark of the certificate and the background introduction of the testing station. For a formal jade appraisal institution, it is absolutely impossible 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 a certificate of accreditation when it passes the laboratory accreditation of China National Accreditation Committee for Conformity Assessment. On this certificate, there will be the full name of the appraisal institution and the number of the certificate of accreditation, and 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 usually 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. At present, the CRBT voice prompt of domestic fixed-line telephones involves the name of a company or company, and it is required to be handled by the business license or the certificate of the company. Therefore, when dialing the fixed-line telephone written on the certificate, the CRBT voice prompt of another company appears, which only shows that the telephone number on this certificate is the telephone number of another company.

2. Data easily misunderstood in the certificate A. Quality: The "quality" on the jade appraisal certificate actually means "weight", not the quality of jade. I learned in middle school physics class that the exact expression of the actual weight of each object is the word "quality". It's just that in everyday life, everyone is used to "weight"; B, when the jadeite has been strung with rope or inlaid with metal during the identification, then "density" is not written as 3.33g/cm? Yes; C, some inspection items that are not tested or evaluated will be represented by "* * * * *". But in the mouth of some merchants, 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 tone, but the basic external characteristics of jadeite can still be compared. The basic external characteristics 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 on the certificate (the error of .1-.5g 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 agency to verify the specific reasons.

Legal basis:

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

Derivative question:

What are the procedures for notarization?

1. Apply.

that is, the parties concerned put forward a request for notarization to the notary office. When applying for notarization, the parties concerned shall submit it to the notary office in person and fill in the notarization application form. If you entrust someone else to handle it on your behalf, you must submit a written power of attorney to the notary office, which should specify the agency matters, authority and time limit, and be signed and sealed by the client. However, when applying for notarization certificate, 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 apply for notarization in person at the notary office, the notary can go to the place where the party concerned is located. State organs, enterprises, institutions, people's organizations and other legal 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 representatives shall submit certificates of representation.
