Second, the most important diamond cutting technology today is in India. Basically, 12 of the world's 13 diamonds are processed in India. However, Antwerp also has diamond processing, but most of them are large diamond processing and characteristic cutting. Due to the high local labor costs in Belgium and Europe, most diamonds processed in Antwerp are of excellent cutting quality, but their prices are mostly higher than the market average. It can also be seen from this point that the Antwerp diamond you mentioned is not the diamond processed by Antwerp.

Third, you ask Antwerp why diamonds are cheaper than ordinary diamonds. From the above points of view, this is purely a "trick" of the merchant, because the processing location of the diamond can not be judged in the later stage, but this statement can make you feel that the diamond seems to be very good, that's all.

Just like this incomprehensible answer upstairs, except for the last two paragraphs, the front is nonsense, so you must be careful when collecting information online.
