The examination may consider optical and physical properties, inclusions, growth features, spectroscopy, microscopy, and other gemological testing appropriate to the material. Laboratory-grown stones can have many of the same fundamental properties as their natural counterparts, while imitation materials merely resemble the gemstone they imitate. GIA identification reports can distinguish natural, laboratory-grown, and man-made materials and disclose detectable treatments.
Heating, fracture filling, irradiation, diffusion, dyeing, laser drilling, and other treatments can alter appearance, durability, care requirements, or commercial representation. An expert can examine whether a treatment is detectable and whether documentation accurately describes the stone. FTC Jewelry Guides address disclosure of gemstone treatments in circumstances where treatments are nonpermanent, require special care, or significantly affect value.
The expert can compare the report number, gemstone description, measurements, weight, color, clarity or other reported characteristics, treatment disclosures, and identifying features with the item being examined. Mounted jewelry can create limitations because some characteristics cannot be assessed as precisely while a stone remains set. GIA's jewelry services, for example, state that grading is performed only to the extent permitted by the mounting.
Useful materials may include the jewelry or loose stones themselves, original grading or identification reports, certificates, invoices, sales descriptions, photographs, packaging, repair records, appraisals, correspondence, warranties, and documentation of prior condition. When authenticity, treatment, damage, or substitution is disputed, preserving the item in its existing condition can make later comparison with the documentary record more reliable.
