I dare not say elsewhere, but I dare to guarantee that the naked diamonds identified by the Shanghai National Inspection will be a laser number above 30 points. This number is a number with the national inspection certificate with your hand. You can go to the jewelry shop to ask for a laser number, and you can also take your diamond to the State Inspection Center on the left of the diamond exchange on the left of the Century Avenue circuit to go to the re -inspection. None of the national inspection will only go out SI1 or SI2. SI and diamonds have to see the impurities inside or internal content in 10 times the big mirror. The P -class diamond does not achieve gem -level diamonds at all. It is generally used in industry. Besides, the P -class diamond can easily see the impurities inside with the naked eye.
I suggest you find a 20 -fold mirror to see the number on the diamond waist that is not corresponding to you,
If the number, then you can find the National Inspection Center The identification results are different, and there is no money for re -examination). I go to the store to refund
