  1. How to enhance the confirmation of the jewelry identification certificate
    Abstract: Jewelry appraisal certificate is the key to quality assurance during the sales process of jewelry. However, the jewelry appraisal certificate issued by many inspection institutions at home and abroad is lacking confirmation to the corresponding physical objects. Therefore, in practice, you need to find and choose the characteristic confirmation characteristics of jewelry and jade, and take one or two in the certificate. Its selection principles can be considered three aspects. The marking method can be enlarged photos or sketches. This work not only has business significance and quality supervision, but also has important legal significance.
    The keywords: jewelry; certificate; real object; confirmation

    Jewelry and jade appraisal certificate (including inspection report) is a certificate of scientific identification and quality inspection of jewelry and jade and its jewelry. Providing the necessary quality inspection certificates in jewelry sales is an important means to implement the country's relevant national product quality laws and regulations, eliminate falsehood, and protect consumers and operators with good rights and operators, and promote the healthy and orderly development of the jewelry industry.
    It to make the appraisal certificate truly plays the above important role. In addition to the authenticity and accuracy of the content marked in the physical appraisal test, the confirmation that the certificate is consistent with the real object is essential. The appraisal certificate is the "ID card" of the corresponding jewelry object. Only by having a confirmation function to the physical object can it be confirmed to confirm the "identity" of jewelry and jade.
    It after the reform and opening up of my country, in the early days of the recovery and development of the jewelry industry, there were no physical photos issued by the gem appraisal certificate issued by some units, which only marked the size and quality of the identified items. Such a certificate is not confirmed to the identified objects, so the possibility of being replaced by the real thing cannot be ruled out. With the improvement and improvement of the quality and technical supervision of the jewelry industry, the identification certificate issued by the jewelry and jade quality inspection agency today has attached color pictures of accessories. As long as the photos used are clear and accurate color, the natural pattern form, structure, and structural characteristics of jewelry can clearly show the characteristics of the jewelry.

    It currently many jewelry and jade appraisal certificates lack the confirmation of the real object

    . According to the author, many jewelry identification certificates at home and abroad lack confirmation of the corresponding physical objects. The reason is that the photos attached to this type of certificate cannot show the personality characteristics of the corresponding physical objects. This situation is particularly existing on the appraisal certificate of diamond jewelry. Due to the small volume, the abrasive form is relatively regular, especially the precepts below 1 carat are almost all round diamond -like. Diamond reflects strong reflection, and the clarity reaches gem level. Generally, it is difficult to see the personality characteristics of confirmation, and the difference between the clarity is not clear, and even imitations such as synthetic cubic oxidation with the same form are difficult to distinguish. The layman often recognizes as long as the physical style in the photo is the same. However, the metal frame is generally made of molds. The same mold style is the same, so it is not confirmed to the jewelry and jade appraisal certificate and the real object.
    Itta, other types of jewelry and jade ring, the volume is often not large. When the clarity is good and the color is uniform, plus the surface reflection, it is difficult to show the characteristic confirmation characteristics on the photo.
    For the above -mentioned identification certificates, if the corresponding jewelry and jade are replaced with color, texture and shape, and size, it is difficult to see in the photo. Although these certificates are marked with the total quality of the jewelry, if the jewelry and jade on it on it, if the density is different, the total quality will change, but the counterfeiter can adjust the total quality by adding metals from the back of the jewelry bracket to make the total quality in order to use it to add the total quality to the total quality of the total quality. Achieve the purpose of counterfeiting.
    The size of the objects used by bracelets and large carvings is generally smaller than the physical size. If the color of the stone is single and does not have personal characteristics, the photos often have the confirmation of the physical object. Although the photo can display the characteristics of the jewelry process and the texture of the craftsmanship, the use of computer simulation carving technology can use other materials to make the same -shaped pupae with other materials. For example, the crystal and glass products with better clarity, sheep fat and chalcedony, amber and rosin are difficult to distinguish in general photos. therefore. The jewelry and jade appraisal certificate belonging to the above situation does not have the confirmation of the real thing, and it loses the pseudo -pseudo ability.
    The personality confirmation characteristics of finding and choosing jewelry and jade

    This I used to pay attention to the confirmation of certificates and physical confirmation in the work of jewelry and jade. For example, the author has issued a diamond ring appraisal report with a diamond of 0.5 carats, because the owner is anxious to go to the country, and even the photos are too late. After the appraisal, I had to draw a diamond sketch in the appraisal report, and drawing the ring of the micro -packet body sketch map next to the appraisal report. One of the parcels is very special, like a cat, and then ask the owner to school in the mirror whether the graphics are accurate, and the signature is made on the report. Two years later, the owner of the diamond wanted to sell this thing to others, but the buyer was not assured, and the owner came to me together to confirm whether the identification report was consistent with the real object. I put the ring under the mirror and adjust the focal length of the parcel position. I found the "cat". Please check it by himself. He confirmed at a glance and said, "It's too bright! Things in this natural stone, and people who have the ability can not be forged!" Of course, this form is unique It is not difficult to find a package with individual characteristics in other diamonds, as well as the situation of other jewelry and jade. The characteristic confirmation characteristics inside the gemstone are best to find the package inside the crystal, such as solid wraps, liquid wraps, gaseous wraps or two -phase, three -phase bags, and so on. Each bag often has its own unique form. The combination of the combination (position, distance, etc.) often has unique personality characteristics. In particular, those bags with identification significance can be used as a confirmation characteristics and an important voucher for identification and testing, which has dual significance. If the body is not significant, you can also choose some special structures of the gem as a confirmation feature, such as growth patterns, ribbons, pores, cracks, and even the damaged forms of surface or edges. As long as this morphological characteristic cannot be copied, naturally it is difficult to reproduce, they can consider the characteristics of identifying personality.
    For jade, the obvious color form, structural form, and large cracks can show the confirmation characteristics in general clear photos. However, for those jade, which are uniform, and texture without decorative colors, they have to find some micro -characteristics of some internal unique forms as the basis. For example, some color dots, cotton cotton balls, fine structure forms, small cracks, etc. can be found under the microscope. Even the sand eye and potholes left by the appearance processing are as long as their shapes are unique. It is not easy to appear the same, and it is difficult to copy artificially. You can also consider the characteristics of identifying personality.
    The personality recognition characteristics of jewelry and jade. In the identification certificate, each piece only needs to be selected one to two. The choice principle has three points: one is that the characteristics are unique and clear, and it is difficult to imitate and fake. The other is in jewelry jewelry The location should be easy to observe. For example, the face -to -face gemstone is best to choose from the crown. It is not inlaid to be inlaid, and it is best not to choose from the bottom surface. Before the large mirror, you can see it clearly to facilitate checking. But for those jewelry and jade with high clarity, such as diamonds, they have to find those subtle personality recognition characteristics under a microscope.

    . The labeling method of confirmation features on the certificate

    In order to facilitate the confirmation between the certificate and the real object, for diamonds and other high -end gems, if the noodles are small, take photos. It is best to enlarge the ring noodles. If confirmation is not displayed on a basement photo, you need to add one or two microcotic photos with individual confirmation characteristics to combine it into a regular block. Keep the beauty on the certificate composition. After the photo is pasted, the personality confirmation characteristics on the micro -photos must be marked with the position and magnification of the full picture. Take photos, pay attention to selecting the light source and adjusting the lighting method, and at the same time control the size required for the image. If you cannot take a micro-photo, you can also refer to the national standard GB / T16554-2002 diamond grading certificate clarity sketch icon method to depict personality confirmation characteristics. However, the depiction cannot be described by symbols. The accurate graphics should be described in a realistic method. The graphic is painted in the place where the micro -photos is applied, and the corresponding position is cited in the full picture of the full picture. Personal confirmation is characterized by the natural password in jewelry and jade. It is labeled with the physical full -picture photos on the jewelry appraisal certificate, which enhances the confirmation and fake function of the certificate consistent with the real object. At the same time Confirmation. This is an effective constraint on the weaknesses that use the lack of confirmation to use the certificate of the certificate, and the migration of responsibility to marrying the responsibility to the adverse motivation of the appraisal agency and the appraiser. Therefore, enhancing the confirmation of the jewelry identification certificate to the real objects not only has business significance and quality supervision, but also has important legal significance. In the assessment report and other vouchers about jewelry and jade assessment work, it can also be used in reference.
