Shopping malls do not recommend it because it is expensive and the quality of diamonds is not good. It is also very important that the diamond rings in shopping malls are all certificates of national inspection.
To be disrespectful, the national inspection certificate is not as accurate as the GIA certificate. Generally, the color of the certificate of national inspection will write D-E, without specifying whether it is D or E, but it is very tricky. D and 80-cent diamonds can differ by thousands! ! !
However, many domestic appraisal institutions are also mixed, and some institutions can upgrade diamonds by giving more money. This is why more and more people tend to customize GIA certificates for loose diamonds.
For diamonds with GIA certificate, the certificate is equivalent to the ID card of the diamond. On the waistline of the diamond itself, a circle of codes consistent with the certificate is engraved, thus forming the relationship between 1 and 1, and no one can forge it. There is no such item in the national inspection certificate, so the finished stone is generally inspected, and the diamond ring photo is attached to the certificate.
Generally, when you buy a loose diamond, the merchant will provide you with some tools, such as a cutting mirror, a magnifying glass, a color comparison card and so on. Believe in your eyes, think that diamonds look good, and which diamond shines is good. Of course, the price has a lot to do with the data on the certificate.
After the diamond is set, don't forget to compare the waist size of the diamond again. A well-made setting will deliberately leave the waist size for you to observe and will not be blocked by the claws on the ring.
If you really don't feel at ease, add a few tens of dollars and let the merchant give you a national inspection certificate.
If you are in Beijing, I suggest you go to Xidan's 109 wedding building, where the price should be the cheapest in Beijing, and they are all GIA certificates, so you can't fake them.
