This is the certificate of China National Jewelry Testing Center. I spent 3000 yuan on this jade. I don't know whether it's true or not, and I don't know how much this jade is worth.
If the certificate is true, this piece is Hetian jade, but the certificate can only test its authenticity, can't identify a reasonable price, can't take a clear picture, or some experts judge its approximate price, and the prices of different channels vary greatly. According to my ten years' experience in playing jade, combined with pictures, the price of this 20-gram blue and white pendant in the national first-class jade market will not exceed 1000.
