Virtuoso Pleiades Citrine is a pear meetpoint gemstone faceting diagram computationally optimized for Quartz, Amethyst & Citrine (Amethyst, citrine, ametrine, smoky quartz, rose quartz, rock crystal) at RI 1.54 (critical angle 40.5°, Mohs hardness 7 Mohs). Cut on a 96-tooth index gear across 67 tiers and 126 total facets, it features a standard crown architecture with a 13.6% table area and a 1.53 length-to-width ratio.

Ranked #1 out of 14 pear patterns at RI 1.54, Virtuoso Pleiades Citrine achieves a composite ray-traced ProFacet optical score of 0.843 across a ±45° viewing tilt envelope—recording 0.587 normalized brightness, 0.991 structured contrast, 0.229 dynamic scintillation, and 0.865 reflection Shannon entropy with 0.657 spectral dispersion (fire). Under 100-run Monte Carlo ±1.0° mast-angle perturbation testing, 9 out of 10 simulated stones retain at least 99.4% of their nominal optical score (p10). Bench workload is rated Competition (FCI 97.4 / 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.
