Overall Assessment
An intriguing natural rough diamond specimen showing authentic geological surface features, growth patterns, and textures, best appreciated in its raw form or professionally evaluated for cutting potential.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Limited due to rough surface and lack of standard facet geometry
Fire
Minimal dispersion in its current rough state
Scintillation
Absent prior to cutting and faceting
Proportions
Natural rough proportions, heavily dependent on future cutting plan
Symmetry
Natural irregular crystal symmetry
Polish
Raw, unpolished natural crystal faces with growth lines (trigons/striations)
Fluorescence
Cannot be determined without UV testing (likely none to faint)
Inclusions
Natural feather fractures, mineral inclusions, and internal cloudiness visible
Blemishes
Natural rough surface pitting, resorption phenomena, and etch channels
Origin
Natural alluvial or primary kimberlite deposit origin
Treatment Detection
No treatments detected (untreated natural rough)
Estimated Value
Varies widely based on potential cut yield; rough specimens typically range from hundreds to low thousands of dollars
Certification Estimate
GIA or similar major lab if submitted as a rough specimen or post-cut certificate
Investment Potential
Moderate as a collector's mineral specimen, highly dependent on successful master cutting
