Are all the jewels of Thai Royal Jewellery real? Who bought it?

This is a place that Thailand Tourism Bureau stipulates that foreign tourists and group tourists must go to, so there will definitely be no holidays. The most important thing here is that the price is outrageous, because only from the perspective of brand packaging, it is also very poor. Secondly, the workmanship is relatively rough, and finally, you can buy gems of the same quality or even better at a 30% discount in China. I bought a red gem ring with more than 2000 RMB and a cracked ruby. Later, I saw one at a domestic jewelry exhibition, and there was no obvious flaw. Although it was optimized, it only sold more than 700 pieces. )
