It is easy to confuse "GRA" with "Gia", which is also the genius of the inventor of GRA's false certificate. It is easier to understand this:
Similar to the difference between "Kang Shuai Fu" and "Master Kong"
So if you have any questions, go to a foreign jewelry appraisal agency for re-appraisal.
Regarding "burning or not", domestic appraisal institutions basically do not look at it.
The picture below is a screenshot of the official website of GIA, so be sure to look for the official website of GIA when surfing the Internet. It's not the so-called GRA
Look at the picture below. This is the official introduction of GRA. It is in English. If English is almost poor, it is still a little hard to read. Look at the title first. I really don't know what "gemology" in the green box means, and there are not enough words. I only know the logic of gemology. In addition, when did English begin to use reduplicated words? There are two studies in the red box, and the rest are English introduction. If the foreign language is better, you can try to translate it.
The picture below shows the back of GRA certificate, which is really similar to the back of GIA certificate. For the time being, the contents in the middle of the certificate are exactly the same as those in GIA, and there is no difference in order. I can say that piracy is a one-to-one copy ~ ~ ~
Let's take a look at the specific content of the certificate and use three certificate numbers to query. We can see that everything on the certificate is exactly the same. Although mosang stone is a synthetic product, it can't be exactly the same. The weight, color, clarity and cutting are all the same. How can this be a certificate? Compared with photocopiers, there seems to be no special difference.
Look at another GRA. The picture below is a screenshot of their official website. It seems that there is still a certain gap with GIA, so at least it has been divided.
The picture below is the official introduction, but we saw a word in this logo, which is seek. I really don't know this word, and I looked it up in the electronic dictionary specially, and I didn't understand what it meant, lamenting that my vocabulary was really limited.
The following are the contents on the front and back of this certificate. We can see that it says "Special Certificate for Mosan Diamond". If it is really clear, it is unrealistic to say that he is faking. At least, we have told you that this certificate is for "domestic Mosang diamond".
However, when we look at the specific contents of the certificate, we will find that it is almost the same as the certificates of other diamonds in the world, and the classification used is similar to that of diamonds, using 4C classification and terminology. Although mosan stone is recognized as the best substitute for diamond at present, the grading standard of mosan stone can only be measured by 4C.
It seems that I can't find this certificate online recently, but someone has, and the answer is the same. All certificates are the same (this obviously shows that GRA's certificates have been copied a lot after the first edition). Although Mosang diamond is a synthetic product, it can't be exactly the same, but if the quantity is large enough, it will lead to the possibility of counterfeiting.
Ok, let's share GRA here. I think everyone knows something about the GRA certificate. I hope that when you buy Mosan diamonds, you can distinguish between genuine and false certificates, and it is more reliable to choose an officially authorized dealer.
