Crystal Verification: The origin and type of crystal are verified using advanced testing methods, including spectroscopy and refractive index analysis.
Natural vs. Synthetic: Clear distinction between natural, treated, and synthetic crystals.
Inclusions: Evaluation of natural inclusions and their impact on value.

2. Clarity Grading

Assesses the visibility of internal and external flaws.
Grading ranges from flawless to heavily included, with detailed descriptions of inclusions such as veils, fissures, or growth patterns.
