Moissanite (Simulant)
Moissanite (Simulant) · Cushion Modified Brilliant
Fair to Good Cut

Carat
3.90 carats
Color
Estimated G-H (Near Colorless)
Clarity
Estimated VS1-VS2 (Very Slightly Included) based on visual surface facets
Shape
Cushion Modified Brilliant
Overall Assessment
This appears to be a high-quality lab-grown Moissanite rather than a natural diamond, characterized by the intense 'rainbow' dispersion of light and the specific doubling of facets visible in the blurred sections of the image. At 3.90 carats, it is a significant fashion stone.
Cut Quality
Fair to Good
Brilliance
High (Brightness is significant due to high refractive index)
Fire
Very High (The image shows excessive rainbow dispersion or 'disco ball effect', characteristic of Moissanite's higher dispersion compared to diamond)
Scintillation
High/Busy (Intense sparkle pattern visible even in low resolution)
Proportions
Deep pavilion and high crown, typical of cushion cuts designed for maximum dispersion (fire)
Symmetry
Good
Polish
Good
Fluorescence
None (Moissanite does not typically show UV fluorescence unlike diamond)
Inclusions
Difficult to distinguish from image; likely microscopic needles common in silicon carbide
Blemishes
Visible facet junction blurring, indicating slight surface softening
Origin
Laboratory-grown (Silicon Carbide)
Treatment Detection
None likely; inherently lab-created
Estimated Value
$100 - $350 USD (Based on market rates for synthetic moissanite)
Certification Estimate
GRA (Global Gemological Research Academy) or similar moissanite-specific lab
Investment Potential
Low (Simulants do not historically hold or appreciate in value)

Setting Suggestions
Platinum or 14k White Gold solitaire setting to complement the white flash and large size
Care & Maintenance
Clean with mild soap and warm water using a soft brush; avoid abrasive cleaners
Interesting Facts
Moissanite has a higher refractive index (2.65-2.69) than natural diamond (2.42), making it more 'fiery'.
