Rough / Raw Natural Diamond
Rough / Raw Natural Diamond · Rough Octahedral Fragment
Uncut / Rough Cut
Carat
3.9 carats
Color
Fancy Light Pinkish Brown / Low Color (K-M range appearance)
Clarity
I3 (Included 3) due to heavy internal fracturing
Shape
Rough Octahedral Fragment
Overall Assessment
This is a 3.9-carat natural rough diamond specimen. It exhibits a high degree of internal fracturing which significantly limits its potential for being cut into a high-clarity polished gemstone but makes it an interesting geological specimen or piece for 'raw' jewelry.
Cut Quality
Uncut / Rough
Brilliance
Low (Diffused light due to rough surface)
Fire
Moderate (Visible prismatic dispersion in light-catching fractures)
Scintillation
Low (Random flash pattern)
Proportions
N/A (Rough stone)
Symmetry
Poor (Irregular rough form)
Polish
None (Natural surface texture)
Fluorescence
Indeterminate from image
Inclusions
Extensive internal twinning wisps, heavy feathers, and internal fracturing
Blemishes
Surface percussion marks and natural growth steps
Origin
Likely African (e.g., DRC or Sierra Leone) based on morphology
Treatment Detection
None apparent; appears as a natural rough state
Estimated Value
$600 - $1,200 (Specimen/Industrial value)
Certification Estimate
GIA Rough Diamond Report; Clarity: I3, Color: Mixed
Investment Potential
Low (High inclusion density limits potential yield if cut)

Setting Suggestions
Wire-wrapped pendant or organic 'raw' engagement ring setting (claws)
Care & Maintenance
Avoid ultrasonic cleaners as high internal fracturing makes it prone to splitting
Interesting Facts
The pinkish hues seen internally may indicate plastic deformation of the crystal lattice
