Likely Diamond Simulant (possibly Cubic Zirconia or Glass)
Likely Diamond Simulant (possibly Cubic Zirconia or Glass) · Poorly faceted Cushion or Radiant hybrid
Poor (asymmetrical faceting and light leakage evident) Cut
Carat
Estimated 2.0 - 3.5 carats based on visual proportions
Color
Estimated J-L (appears to have a warm, brownish-yellow undertone)
Clarity
I2 to I3 (Included), heavy internal graining and possible fractures
Shape
Poorly faceted Cushion or Radiant hybrid
Overall Assessment
The specimen displays characteristics inconsistent with high-quality diamonds, including poor symmetry and suspicious light dispersion. It is likely a simulant or a very low-quality industrial-grade stone.
Cut Quality
Poor (asymmetrical faceting and light leakage evident)
Brilliance
Low (significant light leakage/dead spots in the center)
Fire
High (exaggerated rainbow dispersion suggests a high-dispersion simulant)
Scintillation
Poor (unbalanced light/dark contrast pattern)
Proportions
Non-standard; high crown and shallow pavilion seen in the light extinction patterns
Symmetry
Poor (outline and facet junctions are irregular)
Polish
Fair (surface appears slightly pitted or scratched)
Fluorescence
Indeterminate from image; likely None
Inclusions
Large internal feathers, severe graining, and potential carbon spots
Blemishes
Visible chips on the girdle edges and surface abrasions
Origin
Likely manufactured/synthetic simulant
Treatment Detection
Potential fracture filling to hide significant structural flaws
Estimated Value
$10 - $150 (if simulant); $800 - $1,500 (if low-grade natural diamond)
Certification Estimate
Unlikely to be certified by GIA/AGS due to quality; might receive a general ID report
Investment Potential
None (this is likely a decorative or costume piece)
Similar Diamonds
Low-grade commercial salt-and-pepper diamonds or common CZ
Setting Suggestions
Bezel setting to hide rough girdle and protect edges
Care & Maintenance
Clean with mild soap and water; avoid ultrasonic cleaners due to fractures
Interesting Facts
The exaggerated rainbow effect (fire) often indicates a simulants refractive index is higher or different than a natural diamond
