Today I will tell you a very basic, but very practical trick is how to reply after receiving the certificate, as well as some precautions, 1. How to inquire after receiving the certificate?2 What are the precautions, 3 false certificates and sets of certificates. 
First of all, the first certificate query, in fact, is very simple, I take the egl certificate as an example, after we receive the certificate, open the webpage and enter the certificate on the **, or directly scan the certificate on the *** after scanning will jump to the official**, we enter the corresponding information on the physical certificate according to the prompt, you can**view the certificate information of this stone, at this time, as long as the physical certificate is compared, and **certificate is consistent. 
Second, what are the precautions, I have summarized a few questions, first, why can't I find the information?This is because the laboratory uploads the test data to the official**, not synchronized with the paper certificate we get, it originally took about 10 working days, but since the Lankan economy began to collapse this period began to extend, and some will take a month or even longer, **The query information is also based on the parameters on the physical certificate, and if you can't find the information for the time being, don't panic and wait for a while. 
Second, this mark is burned, is it new or old?Generally speaking, if it is a newly burned bare stone in Lanka, the laboratory will tell you that there is a problem with the stone, and then pay a test fee to let you take the stone back without issuing a certificate, in addition to such factors as synthetic bare stone, bare stone clarity is extremely high, can not identify whether it is natural, etc., the laboratory will give us a receipt and will not issue a certificate by default, so you get the test on the certificate is burned, it only means that it is old burned. 
The third certificate needs to be reissued, it is best not to lose it very troublesomely, some institutions can be directly reissued by virtue of the list of certificates when they are issued, and some institutions need to take the stone to Lanka to reopen, last year a friend lost the certificate of GIC, before and after two months to reissue it, from a different point of view, this is a good thing that it is not easy to have a fake stone set of certificates. 
The third fake certificate and set of certificates, at present, as far as I know, Lanka's certificate agency, there is no fake certificate set of cases, the main reason is that I think the cost of counterfeiting is relatively high, and it is not necessary to build **, reproduce the bare stone or something, but GRS has a fake certificate, the certificate I have seen is too fake, the printing is extremely rough, the font is not the same as the real book, but anyone who has bought colored gems should not be deceived, everyone must be optimistic about the domain name when querying, look for the official ** , but in fact, don't worry too much, I believe that most of the merchants in this market still cherish their feathers, and there is no need to use people who are suspicious.
