Likely Natural Diamond or High-Quality Simulant (Visual indicators suggest potential Natural Diamond based on inclusion patterns)
Likely Natural Diamond or High-Quality Simulant (Visual indicators suggest potential Natural Diamond based on inclusion patterns) · Radiant Cut (Rectangular Modified Brilliant)
Fair; the stone appears to have a shallow crown and deep pavilion, leading to significant light leakage Cut
Carat
Estimated 1.50 - 2.50 carats based on visual scale and proportions
Color
Estimated H-I (Near Colorless) range; exhibits slight warmth in the body of the stone
Clarity
Estimated I1-I2 (Included); significant internal fractures and crystal inclusions are visible to the naked eye
Shape
Radiant Cut (Rectangular Modified Brilliant)
Overall Assessment
A large-looking stone with significant character, let down by heavy internal inclusions that affect both the structural integrity and the light performance.
Cut Quality
Fair; the stone appears to have a shallow crown and deep pavilion, leading to significant light leakage
Brilliance
Moderate; certain areas show 'windowing' where light passes through rather than reflecting
Fire
Low to Moderate; some prismatic color dispersion is visible in the crown facets
Scintillation
Low; the sparkle pattern is disrupted by the heavy inclusion clusters
Proportions
Deep cut; heavy pavilion facets and a large table percentage relative to the crown height
Symmetry
Good; facet alignment appears mostly consistent although the corners show slight asymmetry
Polish
Good; visible surface reflections suggest a decent polish but with some surface graining
Fluorescence
None visible under current lighting conditions
Inclusions
Prominent feathers (fractures) and possible dark crystals visible in the center and bottom left quadrants
Blemishes
Minor surface abrasions and potential nicks on facet junctions
Origin
Likely Earth-mined due to the specific nature of the fracture inclusions
Treatment Detection
No obvious signs of laser drilling or fracture filling, though clarity is naturally low
Estimated Value
$3,000 - $6,500 USD (Significant discount applied for clarity and cut quality)
Certification Estimate
GIA or IGI; likely to be graded as I1/I2 with Good/Fair proportions
Investment Potential
Low; stones in the I-clarity range do not typically appreciate in value and are harder to resell
Similar Diamonds
Commercial grade radiant cuts typically found in mall-tier jewelry stores
Setting Suggestions
A 4-prong or 6-prong platinum or white gold basket setting to provide maximum security for the fractured areas
Care & Maintenance
Avoid ultrasonic cleaners due to significant internal feathers; clean with mild soap, warm water, and a soft brush
Interesting Facts
Radiant cuts were the first square-cut diamonds to have a complete brilliant-cut facet pattern on both the crown and pavilion
