Simulant (likely Cubic Zirconia) · Radiant Cut
Good Cut
Carat
Estimated 1.5 - 2.0 carats based on surface area
Color
Visual equivalent of D-E (Colorless)
Clarity
Visual equivalent of IF to VVS1
Shape
Radiant Cut
Overall Assessment
The stone displays optical properties, specifically excessive fire and rounded facet junctions, consistent with a Cubic Zirconia stimulant rather than a natural or lab-grown diamond.
Cut Quality
Good
Brilliance
Moderate; shows 'sleepy' or hazy light return typical of high dispersion simulants
Fire
High; excessive rainbow dispersion (fire) which is a hallmark of Cubic Zirconia
Scintillation
Broad flash pattern typical of modified brilliant cuts
Proportions
Deep pavilion with a standard radiant-style faceting pattern
Symmetry
Fair to Good
Polish
Good (surface shows some slight rounding of facet junctions)
Fluorescence
Non-reactive visible under standard light; simulant specific
Inclusions
None visible to the naked eye; typical of synthetic simulants
Blemishes
Minor surface abrasions consistent with softer simulant material
Origin
Synthetic / Factory manufactured
Treatment Detection
N/A (base material is synthetic)
Estimated Value
$10 - $50 USD
Certification Estimate
Likely would not be accepted by GIA/AGS as a natural diamond; identifying as CZ
Investment Potential
Low; no resale value as a gem investment
Similar Diamonds
High-quality Moissanite or Lab-Grown Radiant Cut diamonds
Setting Suggestions
Best suited for costume jewelry or silver/low-karat gold plating
Care & Maintenance
Clean with mild soap and water; avoid harsh chemicals and abrasive surfaces due to lower hardness
Interesting Facts
Radiant cuts were developed in 1977 to combine the elegance of emerald cuts with the brilliance of round cuts
