Begin with identity

Find the material identification first. “Jade,” “jadeite jade” and local terms are not always interchangeable. Then check object type, dimensions, weight where stated, color description and identifying photograph.

Treatment language matters

Look for explicit statements about impregnation, dye, coating, wax or other enhancement. “No indications” is not the same wording as an absolute claim that nothing has ever happened to a stone. Read footnotes and scope limitations.

Verify the document

Use the laboratory’s own report-check service where available. Match the report number and object details. A laboratory report records findings at the time of examination; it is not a valuation, ownership history or promise of future condition.
