Hello, let's talk about the National Inspection and GIA The national inspection, that is, the National Jewelry and Jade Quality Supervision and Inspection Center GIA, the American Gem Institute , GIA Certificate is international and most authoritative internationally. There are different places for the two. The national inspection is inlaid and then identified. GIA must identify nude stones. Let's analyze the difference in the identification certificate ( Only make a simple analysis, if you want to know more, you can find me Baidu Hi) The color of the national inspection and appraisal 4C is a large class, such as D-E F-G H i-J and GIA is the duty D E F G clarity. The national inspection is divided into GIA and other GIAs such as VVS1 VVS2. The reason for enough is that the price of the GIA certificate is even more expensive, and it is not necessary. Secondly, the GIA has been tested by the nude stones just now. If the test comes back, it may not be the original one, and the national inspection is inlaid. If you want to buy a naked diamond, you must find a GIA certificate, because the appraisal is more detailed, the diamond's waist bodium and the GIA number, for the preservation you just said, you can preserve the value, as long as the diamond is really not much of the certificate and the certificate is not too big Relationship, if you buy a finished drill, you don’t need to preserve it. If you buy a naked drill, you can still can only answer you. If you don’t understand, you can leave a message to me.
The international certified diamond certificate is GIA certificate, and the national inspection is just a test of finished jewelry! M many manufacturers are directly sold by themselves. You can know the price of Diamonds of the GIA certificate first! 30 diamonds with GIA certificates! The factory price can be discounted! For quality shelf, diamonds above 30 points will be the same as preserved, but it depends on the quality! buy diamond first to see quality!
Both GIA and NGTC certifications are stricter, and don't choose if not. The jewelery in the current mall must have a certificate of NGTC to sell, and other testing agencies do not work. Because NGTC is a national laboratory founded by the testing agency founded by the Ministry of Land and Resources, represents the authority of the Chinese diamond industry, and has the right to supervise and inspect other testing agencies. GIA is a foreign education institution with the ability to detect diamonds. The 4C standard of diamonds is founded by GIA. All the right to speak in the appraisal of diamonds. According to our years of experience, NGTC focuses on the detection of color and clarity, and GIA has the highest requirements for cutting. If you buy diamonds of more than 30 points, it is recommended that you choose diamonds certified in GIA. The differences between the two institutions with a very clarity will not be too large, and GIA is very strict with cutting. For brilliant, it is recommended to choose diamonds certified in GIA. Welcome to see our ZMY diamond online, there are more introductions.
First of all, explain to you what GIA is what is the national inspection GIA is the American jewelry college. It is recognized as the most authoritative detection structure in the world. At the same time, it is possible to grade more than 6 people, so his professionalism is the best . As for the national inspection, you will see if you have a chance. Just look at it. After all, he is not a very professional testing agency, so the last certificate standard is different from GIA. This is why some people buy GIA but found that they have dropped or upgraded after the national inspection? Since I chose GIA to believe his authority, I think I just want to do a true and false identification. The specific level still needs to be based on GIA as the
, so I recommend you to buy a diamond in the GIA certificate. If you want to preserve value, only the National Inspection Certificate is definitely not possible.
