First, it depends on the date of the appraisal class certificate. Secondly, pay attention to the unit and personnel of the certificate. Third, pay attention to the content of the identification certificate. Because from different testing units, the format of the certificate may not be the same, but the basic content contained in it is roughly the same. rn标准的鉴定分级证书应包括以下内容:rn以钻石为例要有证书的名称、形态、大小、重量、净度、颜色、切工和其它物理参数标准,简要评述, And attached photos, the signature of the appraisal personnel (qualification, DGA, GIA, FGA, or HRD), the signature and qualifications of the reviewer, the name and address of the appraisal unit, the special seal of the appraisal unit, the date of signing, etc. Newest anti -counterfeiting identification certificates use anti -counterfeit inks: fluorescent ink, watermark ink, color -changing ink, glare ink, light sensor ink, OVI ink. Anti -counterfeit certificates are generally printed in four -color special color or concave printing. The main anti -counterfeiting methods used in the documents are: Tuanhua, lace, relief, miniature, invisible watermark anti -counterfeiting, ultra -precision pattern, color fiber anti -counterfeiting, anti -copying group flowers, anti -scanning, etc.

Such a certificate is meaningless to everyone, which is equivalent to a piece of waste paper A anti -counterfeit code only corresponds to a specific product. The anti -counterfeit code cannot be reused. The inspection goods will be given a unique anti -counterfeit code by the 12315 Consumer Association, and it can only be used by users r once. n If a bad merchant printed the anti -pseudo code casually, the user will not find this anti -counterfeit code when checking the official website of 12315, or the type of product that is queried does not match, consumers can know that this product is forged.
3 If a bad merchant bought a batch of genuine products and obtained a part of the anti -counterfeit code, and began to produce in batches, then the anti -counterfeit code will be repeated. After the consumer inquiry is successful, others enter the same anti -counterfeit code query again, and this anti -counterfeit code will appear. If you just scratch the anti -pseudo -pseudo -coating input, it is unsuccessful, then this product is likely to be fake. So this method will be found out soon. And bad businesses will not spend special costs to buy genuine products, so as to obtain anti -counterfeit codes.
