Sugar white jade card - more than a year
In recent years, the decline in the price of gold has led many people to turn their attention to the jade collection. At this time, some newcomers will appear. Because it is just getting started, there is no relevant knowledge background, and I don't know how to choose jade. Jade appraisal book has become an important basis for their identification of true and false. However, is the jade identification book really authentic?
First, because the country does not have a specific white jade grading standard, some appraisal organizations often use the experience and eyesight to identify Hetian jade. Due to different institutions and different personnel experience, the results of the appraisal are not exactly the same. . This kind of behavior, which was only based on experience, caused confusion in the market. Some merchants took advantage of the opportunity to fish in troubled waters, which made the market more chaotic.
Yi Shuangting, vice president of the Xinjiang Baoyu Association, said that because there is no uniform standard, some of the identification lines are now identified according to their own identification criteria, that is to say, each has its own methods. In order to open the road to sales, businesses that require quality inspection units to issue sheep fat jade certificates are also everywhere. Some quality inspection units are driven by economic interests and are also satisfied with this requirement. Without a national standard, it is impossible to form a norm, and there are loopholes to be found.
Second, the appraisal agency's identification of seed jade skin color, basically no skin color and sugar color or sugar skin, regardless of fake skin and leather. Although this situation does not involve the true and false issues of Hetian jade, the price impact on Hetian jade is quite large.
3. The appraisal and testing institutions basically abide by the rule of not making the appraisal of the place of origin, and clearly stipulate that the appraisal certificate does not reflect the occurrence or suggestion of the relevant place of origin. According to Yue Yunhui Yuegong, there is no specific index or reference for the identification of the origin of the production. Some characteristics of jade can be artificially manufactured, so that the origin of jade has greater uncertainty. This result has made many consumers feel confused. Even if they hold a certificate, they can't tell whether it is Xinjiang Hetian jade or Russian jade or Qinghai jade. In the end, it is a seed jade or a mountain jade, a mountain stream jade, so there is a collector who says Hetian. Jade's water is very deep, there is no certain appreciation knowledge, never go to sea.
4. The GB/T16552-2003 "Jewelry and Jade? Name" and GB/T16553-2003 "Jewelry and Jade? Identification" standards revised by the state only belong to the recommended standards, thus leaving many appraisal methods for the appraisal institutions. That is to say, you can communicate with each other in these two standards. In this institution, it can be identified as white jade, and in this institution it may be identified as sheep fat jade. Even some appraisers have indiscriminate certificates or even issued fake certificates. You can also check on the Internet. In the back of the interests, can you believe that the certificate is credible?
In this regard, our suggestion is that for the certificate of authentication, it is neither unbelievable nor convincing. When buying a jade, the novice must choose a reputable business, and you must not listen to it. People who like Hetian jade must learn carefully and study hard, and never let people know.
