Likely Simulated (Cubic Zirconia/Moissanite)
Likely Simulated (Cubic Zirconia/Moissanite) · Cushion Brilliant
Good to Very Good Cut
Carat
Estimated 1.5 - 2.0 carats based on typical dimensions
Color
D (Colorless) appearance
Clarity
Internally Flawless (IF) to VVS1 equivalent
Shape
Cushion Brilliant
Overall Assessment
The stone exhibits optical characteristics common in high-quality diamond simulants. The extreme clarity, lack of natural growth features, and intense fire indicate it is likely a decorative synthetic stone rather than a natural diamond.
Cut Quality
Good to Very Good
Brilliance
High surface reflection, though slightly milky in the center due to facet patterns
Fire
Very high; visible spectral dispersion across table facets (rainbow flashes)
Scintillation
Moderate to high with sharp contrast patterns
Proportions
Deep pavilion with a high crown angle and flat table facets
Symmetry
Good; slightly asymmetrical facet junctions
Polish
High gloss finish
Fluorescence
None visible in current lighting
Inclusions
No internal inclusions visible under low magnification; high clarity suggests non-natural origin
Blemishes
Possible minor surface scratching or edge abrasions consistent with softer simulants
Origin
Synthetic/Lab-manufactured simulant
Treatment Detection
No coating visible, likely pure synthetic composition
Estimated Value
$10 - $50 (if CZ) to $200 - $400 (if Moissanite)
Certification Estimate
Likely would not receive a natural diamond report from GIA; standard simulant identification
Investment Potential
Low; simulants generally do not retain or increase in resale value
Similar Diamonds
Standard laboratory-grown Moissanite or high-grade Cubic Zirconia
Setting Suggestions
Platinum or white gold four-prong solitaire setting to enhance colorless attributes
Care & Maintenance
Ultrasonic cleaning or lukewarm soapy water with a soft brush
Interesting Facts
The cushion cut is personal favorite of the Victorian era, often called a 'candlelight cut' for its large facets.
