In fact, you can go to official website, a quality inspector in China, and ask their customer service to run wild, because this certificate is issued by a third party, not a merchant, but you seem to be targeting at the merchant, so you are speechless!
Reply to the landlord's first question: if you are not at ease, you can go to other appraisal institutions for re-inspection. If the test is wrong, you can get the corresponding compensation, but I just checked. The merchant you mentioned seems to have a good reputation and should not sell fakes.
Reply to the landlord and change the question: change the photo again? Don't say that the certificate is not authoritative? Is it wrong to change the text of the appraisal result again? Let's just say that I'm not an expert, but I've been playing jade for almost 10 years. I have seen all kinds of certificates, certificates issued by various testing institutions. I haven't seen the "natural jade" you mentioned! Jade (a), what does a mean? Friends who know a little about jade probably know that the word A is natural. It seems that all testing institutions issue the same words, but some testing institutions issue jadeite (processed), and some are jadeite (filled), something made in 200 yuan ... Hehe, there is no need for merchants to cheat. I think their big company won't give you a refund of this 200 yuan? Incredible, it's not that I say the business is good, but that the landlord is too abnormal. Just now, the certificate said it was not authoritative, and then it was deleted. In other words, I don't know what to do. I won't buy jade if I really don't understand it. It is so boring. If it's really bad, I'll tell them to retire, just a little money. Oh, what a pity. Oh, by the way, I saw that product. It's natural jade, it can't be fake!
