Likely Moissanite or Cubic Zirconia based on high dispersion/fire
Likely Moissanite or Cubic Zirconia based on high dispersion/fire · Radiant Cut
Good Cut
Carat
Estimated 2.5 - 3.5 carats
Color
Near Colorless (G-H equivalent)
Clarity
Eye Clean (VS1-VS2 equivalent)
Shape
Radiant Cut
Overall Assessment
The stone displays dispersion levels (fire) that exceed typical diamond properties, suggesting a high-quality simulant like Moissanite. The radiant cut is well-defined, offering a modern and brilliant appearance.
Cut Quality
Good
Brilliance
High (Bright white light return)
Fire
Very High (Significant rainbow/spectral dispersion seen in facets)
Scintillation
Moderate to High 'crushed ice' effect
Proportions
Large table, shallow crown, rectangular modified brilliant faceting
Symmetry
Good
Polish
Good
Fluorescence
None apparent from image
Inclusions
No significant internal inclusions visible at this resolution
Blemishes
Minor surface reflections and potential facet edge wear consistent with non-diamond simulants
Origin
Synthetic/Laboratory produced
Treatment Detection
None visible; likely inherent synthetic composition
Estimated Value
$50 - $400 USD (based on simulant characteristics)
Certification Estimate
Likely a novelty or simulant certificate if any; GIA/IGI would grade as simulant if not natural/lab-grown
Investment Potential
Low (Simulants do not retain significant resale value)
Similar Diamonds
Crushed ice radiant cut lab-grown diamonds
Setting Suggestions
Four-prong cathedral or halo setting in 14k white gold or platinum
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh chemicals
Interesting Facts
Radiant cuts were the first square-cut diamonds to have a complete brilliant-cut facet pattern on both the crown and pavilion.
