Overall Assessment
An interesting, natural rough diamond crystal displaying characteristic octahedral/elongated habit, ideal for a bespoke organic jewelry design or raw mineral collection.
Cut Quality
Not applicable (Uncut rough specimen)
Brilliance
Low to moderate due to uncut surfaces and rough texture
Fire
Minimal dispersion visible through raw, unpolished crystal windows
Scintillation
Limited flash effect due to lack of standard facet geometry
Proportions
Uncut natural crystal form, depth and table percentages do not apply
Symmetry
Natural asymmetrical rough formation
Polish
Natural unpolished crystal faces with typical striations and trigons
Fluorescence
Cannot be determined definitively without UV testing (typically inert to medium blue in natural rough)
Inclusions
Visible dark mineral inclusion (likely graphite or sulfide) and internal feather fractures
Blemishes
Natural surface pitting, rough skin, and minor edge abrasions
Origin
Alluvial or primary kimberlite pipe deposit origin
Treatment Detection
No treatments detected; appears entirely untreated natural rough diamond
Estimated Value
Varies significantly as a raw specimen, estimated around $300 - $800 depending on cutting yield
Certification Estimate
GIA or similar major lab if submitted as a rough specimen or post-cut grading report
Investment Potential
Moderate value as a collector's specimen or custom bespoke jewelry piece
Similar Diamonds

Setting Suggestions
Organic raw-stone bezel setting in yellow or white gold to highlight its natural crystalline form
