This institution, Liaoning Gemstone Quality Supervision and Inspection Center, really exists. It is the most authoritative gemstone quality inspection institution in Liaoning Province, directly under the National Gemstone Quality Supervision and Inspection Center. It is qualified to issue the jewelry and jade appraisal certificate it has inspected, with corresponding legal responsibilities.

As for the price of Hetian jade you mentioned, I haven't seen the real thing (picture), so I can't evaluate it.
