Possible Simulated/Faux (Likely Cubic Zirconia or glass)
Possible Simulated/Faux (Likely Cubic Zirconia or glass) · Round Modified Brilliant / Multi-faceted Rose Cut Hybrid
Fair to Poor (Asymmetric facets and lack of standard light return) Cut
Carat
Estimated 1.5 - 2.0 carats equivalent by size
Color
Estimated K-M (Visible yellowish/warm tint)
Clarity
Estimated SI2-I1 (Visible clouding and internal textures)
Shape
Round Modified Brilliant / Multi-faceted Rose Cut Hybrid
Overall Assessment
Based on the rounded facet junctions, yellowish tint, and lackluster light return, this specimen is highly likely a non-diamond simulant. It lacks the refractive index and hardness characteristic of a genuine natural or lab-grown diamond.
Cut Quality
Fair to Poor (Asymmetric facets and lack of standard light return)
Brilliance
Low; stone shows windowing and lack of internal reflection
Fire
Low; minimal spectral dispersion despite high-angle lighting
Scintillation
Low to Moderate; lacks the crisp flash of a natural diamond
Proportions
High crown with shallow pavilion characteristics; non-standard geometry
Symmetry
Poor (Uneven facet edges and off-center culet appearance)
Polish
Fair (Softened facet junctions and visible surface pitting)
Fluorescence
Indeterminate without UV light source
Inclusions
Visible cloudiness, potential internal fractures or flow lines consistent with glass/simulants
Blemishes
Surface abrasions and rounded facet edges typical of softer materials
Origin
Factory manufactured (Simulant)
Treatment Detection
No standard diamond treatments visible; material appears homogenous with common simulant wear
Estimated Value
$5 - $50 USD (Assuming it is a simulant based on visual markers)
Certification Estimate
Unlikely to be certified by GIA/AGS due to questionable authenticity; local appraisal recommended
Investment Potential
Negligible; likely a decorative fashion piece with no resale value
Similar Diamonds
Mass-produced faceted glass crystals or vintage costume stones
Setting Suggestions
Costume jewelry or silver-plated settings; silver or low-karat gold-tone fashion jewelry
Care & Maintenance
Avoid ultrasonic cleaners; wipe with a soft cloth and mild soap; keep away from harsh chemicals
Interesting Facts
The large facet structure and rounded edges are classic indicators of older glass paste jewelry or early synthetic simulants.
