IMPORTANT INFORMATION

This app is an educational reference tool. The information provided is for general learning purposes and visual identification reference only. It is NOT a substitute for professional gemological testing or appraisal.

For authentication, valuation, or any decisions involving significant financial value, always consult a certified gemologist (GIA, AGS, or equivalent) who can perform proper testing with calibrated equipment.

The app cannot definitively verify the authenticity, grade, or precise value of diamonds, gemstones, or crystals. Visual identification has inherent limitations and should be used as a starting point for learning, not as final verification.
