Likely Cubic Zirconia or Simulated Stone
Likely Cubic Zirconia or Simulated Stone · Round Brilliant
Good to Fair (faceting appears slightly rounded) Cut
Carat
Estimated 1.5 - 2.0 carats (based on size relative to finger)
Color
Estimated D-E (Colorless)
Clarity
Estimated VVS2 - VS1 (appears relatively eye-clean)
Shape
Round Brilliant
Overall Assessment
The stone exhibits visual characteristics consistent with a diamond simulant, specifically Cubic Zirconia, due to its high fire, rounded facet edges, and lack of diamond-characteristic luster.
Cut Quality
Good to Fair (faceting appears slightly rounded)
Brilliance
Moderate; shows classic glass-like brilliance rather than the sharp light return of a natural diamond
Fire
High; displays significant prismatic dispersion (rainbow flashes) typical of CZ
Scintillation
Moderate to Low; lack of sharp contrast between light and dark facets
Proportions
Standard Round Brilliant proportions; table appears moderately wide
Symmetry
Fair (facet junctions appear slightly misaligned in reflection)
Polish
Good
Fluorescence
Indeterminate without UV light
Inclusions
No significant internal inclusions visible to the naked eye; some light scattering consistent with simulant material
Blemishes
Potential minor surface abrasions consistent with softer synthetic material
Origin
Synthetic/Laboratory Manufactured (Non-Carbon)
Treatment Detection
None detected; material appears homogeneous
Estimated Value
$10 - $50 (if confirmed as Cubic Zirconia)
Certification Estimate
Unlikely to be GIA certified; possibly a fashion jewelry certificate
Investment Potential
None; synthetic simulants do not retain resale value
Similar Diamonds
Standard high-grade Cubic Zirconia or Swarovski Zirconia
Setting Suggestions
Prong or bezel setting in sterling silver or gold-plated mountings
Care & Maintenance
Clean with mild soap and warm water; avoid harsh chemicals and abrasive surfaces to prevent scratching
Interesting Facts
Cubic Zirconia is much heavier than diamond; a CZ of this size would weigh about 1.7 times more than a diamond of the same dimensions
