Carat
Estimated 20.00 - 50.00 carats (Subject to scale)
Color
D-F (Colorless range based on transparency)
Clarity
SI1 - I1 (Visible internal fracture lines and cleavage planes)
Shape
Rough / Uncut (Tabular formation)
Overall Assessment
This is a significant piece of rough diamond material showing excellent transparency but complex internal structural challenges that would require expert planning for polishing.
Cut Quality
N/A (Rough/Uncut state)
Brilliance
Low (Diffused through rough surface texture)
Fire
Moderate dispersion visible on internal planes
Scintillation
Low to Moderate on raw facets
Proportions
Natural tabular habit with conchoidal fractures
Symmetry
N/A (Natural crystal geometry)
Polish
N/A (Natural crystal faces)
Fluorescence
Indeterminable without UV light
Inclusions
Large internal cleavage planes, feathering, and needle-like structures
Blemishes
Natural surface etchings and high-impact fracture scars
Origin
Likely Alluvial African or Russian origin
Treatment Detection
None visible; appears to be raw mined material
Estimated Value
$50,000 - $150,000 (Highly dependent on yield and final clarity)
Certification Estimate
GIA (Rough Diamond Analysis)
Investment Potential
High (as a specimen or for potential large polished yield)
Similar Diamonds
High-quality rough stones from the Cullinan or Marange mines
Setting Suggestions
Collection specimen or custom 'rough' tension setting in 18k white gold
Care & Maintenance
Avoid ultrasonic cleaners due to prominent cleavage planes and reach internal fractures
Interesting Facts
The stone shows classic conchoidal fracture patterns typical of high-hardness minerals like diamond
