Cut Quality
Not Applicable (Uncut rough specimen)
Brilliance
Low (due to rough, unpolished surface acting as a diffuser)
Fire
Minimal visible fire in current raw state
Scintillation
Poor due to lack of standard faceted angles
Proportions
Natural rough proportions, deep unoptimized dimensions
Symmetry
Natural asymmetrical rough formation
Polish
Natural unpolished crystal faces (trigons and striations visible)
Fluorescence
Indeterminate from visual assessment (typically tested under UV)
Inclusions
Internal feather fractures, cloudiness, and crystal inclusions
Blemishes
Natural surface pitting, etch channels, and irregular growth lines
Origin
Alluvial or primary kimberlite pipe deposit (African or Canadian origin likely)

Estimated Value
Varies by specific weight, ranging from $300 to $1,000 as a mineral specimen
