Overall Assessment
This is an authentic, untreated natural rough diamond crystal displaying characteristic surface striations and internal natural inclusions, highly appealing to mineral collectors and custom artisan jewelers.
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low to moderate due to rough surfaces and internal inclusions
Fire
Minimal due to lack of precision facets and surface texture
Scintillation
Limited, reflecting light irregularly off natural crystal faces
Proportions
Natural uncut proportions with uneven depth and no table or pavilion facets
Symmetry
Natural crystal asymmetry
Polish
Raw crystal surfaces with natural growth lines (trigons/striations)
Fluorescence

Inclusions
Feathers, carbon spots, and mineral inclusions visible internally
Blemishes
Natural surface fractures, rough patches, and indentations

Treatment Detection
No signs of artificial treatment; completely natural untreated rough stone
Estimated Value
Varies by weight and specific purity, roughly $200 - $600 USD as a collector's mineral specimen
Certification Estimate
GIA or similar major lab would issue an authenticity report for the rough stone, likely uncerted for specific color/clarity grades until cut
Investment Potential
Low investment liquidity as a rough specimen compared to certified cut and polished investment stones
Similar Diamonds
Other unpolished alluvial rough diamond crystals of similar size and near-colorless grade
Setting Suggestions
Best kept as a raw mineral specimen or set in an organic wire-wrap or custom bezel setting to preserve its raw nature
Care & Maintenance
Store separately to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
