Yunnan Jewelry and Jade Quality Supervision and Inspection Institute has passed the national inspection, and the certificates are all right. The key is to see if they are consistent with your real thing. I went to the website to check it for you.

The emerald in the certificate photo has a good color. My valuation is within 1000. If the object is more transparent and shiny than the photo, the value will be higher. The trading environment is different and the price is different. Shopping malls and tourist areas have higher transaction prices. Of course, if you don't see the real thing, there will be errors in the valuation. I hope the answer can help you.
