It's a little difficult to identify at home. We can calculate the density and mass of palladium, but it must be very accurate! Personally, I think that you spend so much money on jewelry, don't care about spending so much money for identification. I've done it. It's not too much trouble, and it's not very expensive. Better than worrying at home all day, don't you think? Hmm. How interesting

Reply: I commented in Lijiang, Yunnan, and every province has it. It's an official national appraisal, and Guangzhou should also have it. The specific address depends on your specific city. You can find it online: the name of your city+"Quality and Technical Supervision and Testing Center". The price should be around 200 yuan, depending on how much money you have! I hope I can help you!
