N/A (Uncut rough stone) Cut
Carat
Estimated 1.5 - 3.0 carats based on finger scale
Color
Visual E-F (Colorless)
Clarity
Estimated SI1 to I1 (due to visible surface cleavage and internal growth lines)
Shape
Rough / Uncut (Macle-like or Irregular Octahedron fragment)
Overall Assessment
A high-quality piece of colorless rough diamond with promising transparency, showing characteristic growth features but requiring professional mapping to avoid internal stress planes.
Cut Quality
N/A (Uncut rough stone)
Brilliance
Low (typical for uncut rough)
Fire
Low (requires faceting for light dispersion)
Scintillation
Minimal (light reflects off external crystal faces)
Proportions
Elongated irregular crystal with visible trigons and growth steps
Symmetry
N/A (Natural crystal asymmetry)
Polish
N/A (Natural skin texture)
Fluorescence
Cannot be determined without UV light
Inclusions
Internal graining, cleavage planes, and possible mineral crystals
Blemishes
Surface trigons, percussion marks, and natural skin textures
Origin
Alluvial or Primary Source (Likely Africa or Russia)
Treatment Detection
None apparent; looks like untreated natural rough
Estimated Value
$800 - $2,500 (highly dependent on yield and final clarity after cutting)
Certification Estimate
GIA Rough Diamond Rough Analysis Report (Estimated D-F color potential)
Investment Potential
Moderate; value is unlocked once faceted and polished into a gem
Similar Diamonds
Uncut white octahedrons or rough macle diamonds
Setting Suggestions
Custom rough diamond setting, bezel-set pendant, or rustic claw ring
Care & Maintenance
Ultrasonic cleaners are risky if internal cleavages are present; use warm soapy water and soft brush
Interesting Facts
The surface shows 'trigons,' which are triangular growth marks unique to natural diamonds formed deep in the earth
