Not Applicable (Rough Stone) Cut
Carat
Estimated 3.50 to 4.50 carats based on visual dimensions

Included (I1 - I2) due to surface etching, dark mineral spots, and internal fracturing visible in rough form
Shape
Uncut Rough Crystal / Irregular Elongated Form
Overall Assessment
This is an authentic, natural rough diamond crystal showing characteristic growth lines, surface etching, and mineral inclusions, presenting a unique raw aesthetic or strong potential for custom faceting
Cut Quality
Not Applicable (Rough Stone)
Brilliance
Low to moderate due to rough, unpolished surface scattering light
Fire
Obscured by rough exterior surface and lack of facets
Scintillation
Minimal in current rough state; will depend on final cut and faceting
Proportions
N/A for rough stones; exhibits natural elongated octahedral or macle-like distortion
Symmetry
Asymmetrical, typical of natural rough crystal habit
Polish
Natural crystal faces (trigons, striations, and rough skin), unpolished
Fluorescence
Unable to determine without UV testing; likely None to Medium Blue
Inclusions
Pinpoints, internal feathers, carbon spots, and epigenetic staining along cleavage planes
Blemishes
Natural surface etch channels, triangular growth marks (trigons), and pits
Origin
Alluvial or primary kimberlite pipe deposit (African or South American origin likely)
Treatment Detection
No treatments detected; completely untreated natural rough mineral specimen
Estimated Value
Depends heavily on yield after cutting; approximately $1,500 to $3,500 USD as rough specimen
Certification Estimate
GIA or IGI would classify this as Natural Rough Diamond, uncertified for weight/grade until cut
Investment Potential
Moderate, primarily valued as a collector specimen or for custom lapidary work with potential high yield if cut skillfully
