Simulant (Likely Cubic Zirconia) · Radiant Cut
Good Cut
Carat
Approximately 3.00 to 4.00 carats
Color
D (Colorless)
Clarity
Internally Flawless (IF) visual estimate
Shape
Radiant Cut
Overall Assessment
Based on the intense fire, photographic clarity, and facet junction appearance, this is identified as a high-quality diamond simulant, likely Cubic Zirconia.
Cut Quality
Good
Brilliance
High; shows strong white light return.
Fire
Very High; exhibits excessive rainbow dispersion characteristic of CZ rather than diamond.
Scintillation
Moderate; the light pattern is somewhat blocky compared to natural stone.
Proportions
Deep pavilion with a standard table size; slightly rounded corners typical of simulants.
Symmetry
Very Good
Polish
Good
Fluorescence
None
Inclusions
No internal inclusions visible under photographic magnification; characteristic of synthetic materials.
Blemishes
Minor surface abrasions on facet junctions, common in softer simulant materials.
Origin
Synthetic/Lab-manufactured simulant.
Treatment Detection
None detected; manufactured as a finished product.
Estimated Value
$20 - $50 USD
Certification Estimate
Unlikely to be graded by GIA as a diamond; would likely be identified as Cubic Zirconia by any gemological lab.
Investment Potential
None; simulants do not retain resale value.
Similar Diamonds
Natural Radiant cut diamonds of this size would cost over $30,000 depending on color/clarity.
Setting Suggestions
Ideal for costume jewelry or sterling silver travel rings.
Care & Maintenance
Clean with mild soap and water; avoid harsh chemicals and abrasive surfaces as CZ is prone to scratching.
Interesting Facts
Cubic Zirconia has a higher dispersion rate (0.058-0.066) than diamond (0.044), which is why it reflects more rainbow colors.
