Jewelry and jade appraisal needs to be certified by a professional institution with appraisal qualification before it has legal effect. General jewelry stores do not have relevant appraisal qualifications, and the appraisal certification of jewelry stores is not recognized. Even if there is an appraisal, there will be no appraisal book, and the accuracy cannot be guaranteed. You can go to the National Jewelry Quality Supervision and Inspection Center, the National Jewelry Quality Supervision and Inspection Center and other authoritative institutions for quality inspection and appraisal.
