-
Gemstone condition and quality
-
Natural, treated, or synthetic indicators when identifiable
-
Market-related considerations when relevant

Documentation for insurance, estate, or appraisal-related purposes
Evaluation goals may vary depending on the type of gemstone and the purpose of the documentation.
