Overall Assessment
An interesting and genuine natural diamond crystal displaying characteristic octahedral growth features, ideal for custom organic jewelry design or mineral collection.

Not applicable (Rough, unpolished crystal)
Brilliance
Low due to rough, unpolished exterior surfaces
Fire
Minimal dispersion observed through raw exterior faces
Scintillation
Limited, primarily flashes of light from natural crystal windows
Proportions
N/A for rough stones; elongated crystal habit
Symmetry
Natural asymmetrical crystal growth
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Cannot be definitively determined without UV testing, likely None to Faint
Inclusions
Internal cleavage planes, cloud-like zones, and dark mineral inclusions
Blemishes
Natural surface etching, rough skin, and adhering matrix minerals

No treatments detected; completely untreated natural rough
Estimated Value
$1,000 - $3,000 depending on cutting potential and final yield
Certification Estimate
GIA would issue a Diamond Rough Report detailing weight and measurements
