The invoice for buying things will not indicate the diamond grade, but only the diamond certificate, because diamonds can only be identified by professional institutions, and it is impossible for the store to write them down for you.

But you can go to the testing center to check whether the grade he gave you is not, and the price is tens of yuan.

The ring is 2270 yuan. If it is 16 minutes, the price of loose diamonds for H-color VS is 1400, and the withdrawal is around 2000, so the price is still very cheap. After all, it was bought in Xie Ruilin.

As for pendants and necklaces, less than 1000 RMB is also very cheap.
