Is the ngtc certificate reliable?
First of all, domestic testing centers are much stricter than GIA IGI HRD in clarity color rating. After all, if GIA is a commercial organization, the main direction of testing is to cut the fire color, and the fire color is better. If the naked eye can't tell the color, there is actually no difference. Therefore, the domestic test certificate of the double-certificate finished ring will be downgraded, but now there are cases where the same parameters are given according to the waist code. Secondly, the certificate of the finished ring is of little significance, because many parameters are not marked, so the authority still gets the certificate of bare diamond. The only recognition is that the purity and color of China's certificate of finished products may be more standard.

Although NGGC, like NGSTC, is called National Gold and Silver Products Supervision and Inspection Center, its authority is far from perfect. As a distributor, NGSTC NGTC is very strict with the goods submitted for inspection, and NGSTC is even more strict. It's just that NGTC is more famous.
