Cubic Zirconia (CZ) or Synthetic Simulant
Cubic Zirconia (CZ) or Synthetic Simulant · Princess Cut (Square Modified Brilliant)
Very Good Cut
Carat
Estimated 1.50 to 2.00 carats visually
Color
Colorless (equivalent to D-E on diamond scale)
Clarity
Eye-Clean (simulated IF/VVS quality)
Shape
Princess Cut (Square Modified Brilliant)
Overall Assessment
This stone is a visually appealing square-cut colorless simulant (likely cubic zirconia) mimicking a high-color, high-clarity princess cut diamond, suitable primarily for fashion and costume jewelry rather than fine investment jewelry
Cut Quality
Very Good
Brilliance
High white light return, though slightly glassy compared to natural diamond
Fire
Excessive fire/dispersion compared to a genuine diamond due to higher refractive index dispersion
Scintillation
Good flash effect with broad light and dark areas characteristic of step-cut/modified brilliant corners
Proportions
Standard square face-up appearance with high crown and deep pavilion typical of synthetic simulants
Symmetry
Good to Very Good
Polish
Good
Fluorescence
None observed
Inclusions
None visible under standard magnification; characteristic of synthetic simulants
Blemishes
Minor surface wear or polishing lines possibly present
Origin
Laboratory synthesized simulant
Treatment Detection
No natural treatment applicable; manufactured directly as a simulant material
Estimated Value
Low market value (typically under $50 USD as a simulant)
Certification Estimate
Not typically certified by major labs like GIA or AGS due to being a simulant
Investment Potential
None; simulant stones do not appreciate in value and have minimal resale value
Similar Diamonds
Comparable to high-grade lab-created colorless synthetic cubic zirconia or lead-free glass simulants
Setting Suggestions
Best set in sterling silver, platinum-plated brass, or fashion settings with protective prongs on the four corners
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh chemicals and ultrasonic cleaners if coated
Interesting Facts
Cubic zirconia has a lower hardness (8.0-8.5 on the Mohs scale) compared to diamond (10), making it more susceptible to scratching over time
