There is a Peking University Jewelry Appraisal Center in Wanshan Jewelry City, Tianbei 4th Road, Futian District, Shenzhen. If it is jade without a certificate, it is recommended to go to Peking University Appraisal Center for appraisal (65,438 yuan +00 yuan/piece, and issue an authoritative appraisal certificate, but it will take at least 2 hours). You can ask at the jade sales counter in Wanshan Jewelry City. Generally, we will look at the goods on the spot, and S will give the price. My personal experience is that several jewelry stores (mainly selling jadeite) outside Wanshan Jewelry City generally bid higher. They are all wholesale businesses, so the price will be lower.

Landlords don't have to rush to trade with a certain house, they can ask the receiving prices of several houses and choose the one with the highest bid to trade.
