If it's 30, where did you buy it? Regular store purchases generally do not fake ~ is there a certificate? If so, you can check it online according to the certificate. What is the price? A diamond ring with a 30-point single diamond is generally valued at more than 3,000. If it is much lower than this price, it is undoubtedly fake. Besides, if it is really 30 carats, I don't even know how big this diamond ring is! ! It can fly directly to the jewelry and jade inspection center in big cities such as Shenzhen for direct inspection. After all, if you can afford a 30-carat gadget, you don't care about the plane ticket and the inspection fee, so please ask an expert to go home and have a look. Not bad. Just kidding, hehe.
