Effulgent Sunbeam Moissanite is a octagon meetpoint gemstone faceting diagram computationally optimized for Synthetic Moissanite (Silicon Carbide) (Colorless, blue, green, cyan & champagne lab-grown moissanite) at RI 2.67 (critical angle 22.0°, Mohs hardness 9.25 Mohs). Cut on a 96-tooth index gear across 9 tiers and 50 total facets, it features a standard crown architecture with a 30.4% table area and a 1.00 length-to-width ratio.

Ranked #249 out of 870 octagon patterns at RI 2.67, Effulgent Sunbeam Moissanite achieves a composite ray-traced ProFacet optical score of 0.987 across a ±45° viewing tilt envelope—recording 0.886 normalized brightness, 1.016 structured contrast, 0.912 dynamic scintillation, and 0.972 reflection Shannon entropy with 1.441 spectral dispersion (fire). Under 100-run Monte Carlo ±1.0° mast-angle perturbation testing, 9 out of 10 simulated stones retain at least 95.9% of their nominal optical score (p10). Bench workload is rated Expert (FCI 62.0 / 100). Instant download includes the printable PDF cutting instruction sheet (pavilion, girdle, and crown angles, index settings, cutting sequence, and meetpoint diagrams) plus the 3D FSL source file and workshop cutting license.
