Not Applicable (Uncut Rough)
Brilliance
Low due to lack of facets and rough surface texture
Fire
Minimal due to uncut nature and lack of dispersion angles
Scintillation
Absent due to unpolished and uncut surfaces
Proportions
Not Applicable for rough material
Symmetry
Natural Asymmetric Crystal Formation
Polish
Natural Rough Surface (Unpolished)
Fluorescence
Cannot be determined without UV testing (Likely Faint to Medium)
Inclusions
Heavy internal clouding, feather fractures, and potential crystal inclusions visible
Blemishes
Natural surface etching, trigons, and rough cleavage planes
Origin
Alluvial or primary kimberlite pipe deposit (Africa or South America typical)
Treatment Detection
No treatments detected; completely natural raw state
Estimated Value
$500 - $1,500 USD (Industrial to low-grade jewelry rough)
Certification Estimate
