- Refractometer Baseline: Calibrate to Air (RI 1.000). Place stone table-down over test prism. Verify natural diamond band between 2.410 and 2.420.
- Deep UV Transmittance: Place colorless stone on screening stage. 254nm excitation absorption indicates Type Ia natural aggregated nitrogen.
- Optical Verification: Use 1000X magnification viewport with P3 PPM reticle grid overlay for accurate girdle and inclusion measurements.
