Overall Assessment
An interesting, natural rough diamond crystal showing characteristic growth features, ready either for custom raw jewelry design or professional cutting and polishing.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Low to moderate due to unpolished and rough nature
Fire
Limited due to lack of standard facet angles
Scintillation
Minimal until cut and polished
Proportions
Natural crystal habit, non-standardized proportions
Symmetry
Natural octahedral crystal symmetry with irregular growth lines
Polish
Natural unpolished crystal faces (trigons and striations visible)
Fluorescence
Indeterminate from visual inspection (typically inert to medium blue in natural rough)
Inclusions
Internal mineral crystals and feathers typical of untreated rough
Blemishes
Natural surface pitting, trigons, and rough edge wear
Origin
Likely alluvial deposit or primary kimberlite pipe origin
Treatment Detection
No signs of artificial treatment; completely natural untreated crystal
Estimated Value
Variable depending on final cut yield, roughly $1,000 - $3,000 as a rough specimen
Certification Estimate
GIA or similar major laboratory would grade it post-cut as a natural rough inspection report
Investment Potential
Collectible value as a raw mineral specimen; appreciation depends on raw diamond market trends
