Good Cut
Carat
Estimated 2.50 to 3.50 carats
Color
Estimated D-E (Colorless)
Clarity
Estimated VVS2-VS1
Shape
Cushion Modified Brilliant
Overall Assessment
The stone exhibits characteristics common in high-quality simulants, such as extreme whiteness and high fire, though a definitive test via refractometer is required.
Cut Quality
Good
Brilliance
Moderate; showing some internal dark areas (extinction)
Fire
High; strong spectral dispersion visible on the right crown facets
Scintillation
Broad flash pattern; lacks the fine grain scintillation of a high-end natural diamond
Proportions
High crown with a relatively flat top table; slightly shallow pavilion based on windowing
Symmetry
Fair to Good
Polish
Good
Fluorescence
None apparent from image
Inclusions
No distinct internal inclusions visible at this resolution; appears very clean
Blemishes
Minor surface abrasions consistent with softer materials like CZ
Origin
Likely manufactured (synthetic simulant) based on facet sharpness and fire
Treatment Detection
None visible; material appears homogenous
Estimated Value
$50 - $400 USD if simulant; $8,000 - $15,000 if Lab-Grown; significantly higher if Natural
Certification Estimate
Likely uncertified or a generic lab report; GIA/IGI if it were natural/lab diamond
Investment Potential
Low; simulants and large lab-grown diamonds generally do not hold high resale value
Similar Diamonds
Cushion cut lab-grown diamonds or large-gauge moissanite stones
Setting Suggestions
Double-claw prongs in a platinum or 14k white gold solitaire setting
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid ultrasonic cleaners if the material is unknown
Interesting Facts
The 'crushed ice' effect in cushion cuts is designed to maximize sparkle while hiding inclusions
