Overall Assessment
An intriguing, sizable natural rough diamond crystal displaying characteristic surface features, internal fractures, and inclusions, offering potential for custom cutting or preservation as a mineral specimen.
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Low due to rough, unpolished surface facets
Fire
Minimal dispersion visible through raw crystal walls
Scintillation
Limited flash due to lack of standard pavilion and crown facets
Proportions
Natural crystal proportions, non-standardized
Symmetry
Natural asymmetrical octahedral/dodecahedral growth form
Polish
Natural rough crystal faces (trigons and striations visible)
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Internal cleavage planes, fractures, and brownish mineral spots
Blemishes
Natural surface textures, pitting, and resorption features
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin typical)
Treatment Detection
No evidence of artificial enhancement; completely untreated natural rough
Estimated Value
Variable depending on final cut yields, roughly $1,000 - $3,000 as a rough specimen
Certification Estimate
GIA rough diamond report or local gemological laboratory grading
Investment Potential
Moderate as a collector specimen, high potential value retention depending on cut yield
