Moissanite (Simulant)
Moissanite (Simulant) · Radiant Cut (Rectangular Modified Brilliant)
Very Good (Modified Brilliant faceting) Cut
Carat
Estimated 2.0 - 2.5 Carats (approx. 8x6mm visually)
Color
D-E-F Range (Colorless)
Clarity
Estimated VVS1 - VVS2 (Eye Clean)
Shape
Radiant Cut (Rectangular Modified Brilliant)
Overall Assessment
This stone exhibits the 'double refraction' and high dispersion typical of synthetic Moissanite. While it mimics a diamond's brilliance, the intense rainbow flashes and facet doubling suggest it is a high-quality radiant-cut simulant rather than a natural carbon diamond.
Cut Quality
Very Good (Modified Brilliant faceting)
Brilliance
High (Silvery-white light return)
Fire
Extreme (Rainbow 'disco ball' effect characteristic of Moissanite's high dispersion)
Scintillation
High; rapid flashes of spectral color across the pavilion
Proportions
High crown, shallow table appearance typical of radiant simulants
Symmetry
Good to Very Good
Polish
Good
Fluorescence
None (Not applicable to Moissanite)
Inclusions
Possible needle-like inclusions or 'pipe' features; doubling of back facets visible
Blemishes
None visible at this magnification; surface appears smooth
Origin
Lab-Grown (Silicon Carbide)
Treatment Detection
None (Standard lab production process)
Estimated Value
$150 - $400 (Market value for high-quality loose Moissanite)
Certification Estimate
GRA (Global Gemological Research Association) for Moissanite, D Color, VVS1
Investment Potential
Low (Moissanite is a consumer luxury good, not an investment-grade gemstone)
Similar Diamonds
GIA Certified Radiant Cut Diamond, J Color, SI1 Clarity
Setting Suggestions
Four-prong cathedral setting in 14k white gold or platinum to enhance colorless properties
Care & Maintenance
Clean with mild soap and water; avoid 'oil film' buildup by using a soft toothbrush
Interesting Facts
Moissanite has a higher refractive index (2.65) and more fire (dispersion) than a diamond
