Likely Diamond Simulant (e.g., Cubic Zirconia)
Likely Diamond Simulant (e.g., Cubic Zirconia) · Modified Cushion Cut
Good to Fair Cut
Carat
Estimated 2.50 to 3.50 carats based on visual depth and surface area
Color
D-E range (Colorless)
Clarity
Eye-Clean (Estimated VVS or Flawless equivalent if synthetic)
Shape
Modified Cushion Cut
Overall Assessment
The stone exhibits visual characteristics (excessive fire and facet edge wear) consistent with a diamond simulant like CZ rather than a natural or lab-grown diamond.
Cut Quality
Good to Fair
Brilliance
High; sharp white light return
Fire
Very High; the large rainbow flashes (dispersion) are disproportionately high compared to a natural diamond
Scintillation
Large, blocky light patterns rather than refined 'crushed ice' or 'brilliant' sparkle
Proportions
High crown with a relatively flat table and deep pavilion typical of many simulants
Symmetry
Fair; some facet misalignment noted at the corners
Polish
Good
Fluorescence
Indeterminable from photo; often None in high-quality simulants
Inclusions
None visible at this magnification (typical of lab-grown simulants)
Blemishes
Minor surface abrasions visible on facet junctions, indicative of lower hardness than diamond
Origin
Laboratory manufactured (Synthetic simulant)
Treatment Detection
N/A; homogeneity suggests synthetic production without post-growth treatments
Estimated Value
$10 - $100 as a simulant; $15,000+ if natural depending on specs
Certification Estimate
Unlikely to receive GIA grading if simulant; otherwise would be graded for color/clarity only
Investment Potential
Low; simulants do not retain significant resale value
Similar Diamonds
Crushed-ice cushion cut diamonds or Moissanite with high dispersion
Setting Suggestions
Prong setting in silver or white gold to maximize light entry
Care & Maintenance
Clean with mild soap and water; avoid harsh chemicals as simulants can cloud over time
Interesting Facts
The 'rainbow' effect seen on the right side of the stone is a classic indicator of high dispersion, often exaggerated in non-diamond stones.
