Does the jewelry appraisal book that can be found online indicate that all the treasures identified are true?
Prove it is true! However, tests also have categories! (For example: diamond grading' gold fineness' and so on. ) like some certificates (for example: 18K or D0.50ct)! The category of this note has not been checked again! It's only marked according to the lettering inside the jewelry rack, and it can't be 100%.
