Overall Assessment
The stone exhibits visual characteristics (extinction patterns and dispersion) most consistent with a high-quality Cubic Zirconia simulant rather than a natural diamond.
Cut Quality
Good
Brilliance
High surface reflectivity, typical of high-RI simulants
Fire
High; dispersion levels suggest a material like Cubic Zirconia rather than natural diamond
Scintillation
Moderate; larger facet patterns create distinct light flashes
Proportions
High crown with a medium table; slightly deep pavilion based on edge reflections
Symmetry
Fair to Good; slight variations in facet alignment across the pavilion
Polish
Good
Fluorescence
None apparent from visual inspection
Inclusions
No visible internal inclusions at 1x magnification
Blemishes
Minor surface abrasions consistent with non-diamond simulants
Origin
Synthetic/Man-made
Treatment Detection
N/A; characteristic of synthetic CZ production
Estimated Value
$20 - $100 USD (Simulant market value)
Certification Estimate
Likely ungraded by GIA/AGS; typically sold as simulated gem material
Investment Potential
Low; decorative/fashion jewelry value only
Similar Diamonds
Comparable to high-quality Swarovski Zirconia or Moissanite
Setting Suggestions
Four-prong cathedral setting in Sterling Silver or 14K White Gold
Care & Maintenance
Avoid harsh chemicals; clean with warm soapy water and a soft brush regularly
