Estimated 1.5 - 2.0 carats based on dimensions
Color
Colorless (Equivalent to D-F range)
Clarity
IF to VVS (Eye-clean, typical of simulants)
Shape
Radiant-cut / Square Radiant
Overall Assessment
This stone exhibits the characteristic high fire and 'rainbow' dispersion of a high-quality Cubic Zirconia. While visually striking, its optical properties and facet junction softness identify it as a diamond simulant rather than a natural or lab-grown carbon diamond.
Cut Quality
Good to Very Good
Brilliance
High, but exhibits the 'glassy' luster typical of CZ
Fire
Very high dispersion, showing pronounced rainbows exceeding natural diamond limits
Scintillation
Strong, with distinct colorful light patterns
Proportions
High crown with a deep pavilion, typical of radiant-style simulant cuts
Symmetry
Good
Polish
Very Good
Fluorescence
None visible, but high internal dispersion mimics fluorescence
Inclusions
No apparent natural inclusions; stone appears internally flawless
Blemishes
Slight rounding on facet junctions, typical of softer simulant materials
Origin
Synthetic/Man-made (Laboratory)
Treatment Detection
None; material is synthetic by nature
Estimated Value
$10 - $40 USD
Certification Estimate
Unlikely to be graded by GIA as a diamond; would be labeled as simulant/CZ
Investment Potential
Low to None; mass-produced decorative stone
Similar Diamonds
High-quality Moissanite or Swarovski Zirconia
Setting Suggestions
Prong setting in silver or inexpensive white gold for fashion jewelry
Care & Maintenance
Clean with warm soapy water; avoid harsh chemicals that can dull the surface
Interesting Facts
Cubic Zirconia is denser than diamond, so a CZ of this size would weigh more than a diamond of the same dimensions.
