Excuse me, is the certificate of jewelry and jade from Ruili Inspection Station of Yunnan Dehong Quality and Technical Supervision Bureau credible?
The appraisal certificate issued by the monitoring station is true and absolutely reliable, but who knows whether it is fake or not, and you can't go to Ruili to verify it. If you don't buy jadeite with the length of 1000-3000, it's very interesting to collect it. If you buy it, don't worry about it.
