Natural rough diamond crystal embedded in matrix
Natural rough diamond crystal embedded in matrix · Rough crystal / Irregular octahedral fragment
Not applicable (uncut rough specimen) Cut
Carat
Estimated 2.5 to 3.5 carats in rough state
Color
Near-colorless to light yellow (approx. G-J range)
Clarity
I1 to I3 due to prominent natural inclusions, fractures, and surface reaching features
Shape
Rough crystal / Irregular octahedral fragment
Overall Assessment
This is an authentic natural rough diamond specimen showing classic geological features, growth lines, and inclusions, best appreciated as a raw mineral collectible or custom organic jewelry piece
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low in current rough state, requires cutting and polishing to exhibit brilliance
Fire
Subdued in rough form, potential for moderate fire once faceted
Scintillation
Minimal to none due to lack of flat polished facets
Proportions
Not applicable for rough uncut diamond
Symmetry
Natural crystal symmetry (distorted octahedral/dodecahedral)
Polish
Natural rough unpolished surface with typical crystal trigons and etch channels
Fluorescence
Unable to determine without UV testing (likely Faint to Medium Blue)
Inclusions
Feathers, clouds, internal cleavage planes, and dark carbon spots visible
Blemishes
Natural surface pitting, rough skin, and matrix adherence
Origin
Alluvial or primary kimberlite pipe deposit (African or Canadian origin likely)
Treatment Detection
No treatments detected; completely untreated natural rough specimen
Estimated Value
Lower market value as a rough specimen ($200 - $600 USD depending on exact weight and cut potential)
Certification Estimate
GIA or EGL (would receive a rough stone report or preliminary grading with severe clarity deductions if faceted)
Investment Potential
Low to moderate for commercial jewelry use; higher collector value for mineral specimens

Setting Suggestions
Organic raw-stone bezel setting in yellow or white gold to preserve its natural geological character
Care & Maintenance
Avoid harsh impacts which could exploit natural cleavage planes; clean gently with warm soapy water
