Polish & Symmetry

Polish recounts abrasion on facets; symmetry tracks junction precision. Both interplay with overarching cut—even “Triple Excellent” can still conceal painting / digging artefacts without HD video.

• Poor polish manifests as microscopic streaks scattering light inconsistently.
• Off-centre tables or wandering culets degrade contrast patterning even if symmetry grade reads VG.
• Reflectors / Angular Spectrum maps remain the fastest consumer gut-check—not just spreadsheets.
• Fancy cuts carry extra symmetry tolerances alongside length-to-width taste thresholds.
