Overall Assessment
An intriguing, natural uncut diamond crystal displaying characteristic rough features, growth lines, and internal inclusions, offering a unique raw aesthetic prized by collectors of mineral specimens
Cut Quality
Not applicable as this is a rough, uncut crystal
Brilliance
Limited due to rough surface and internal fractures, but shows vitreous to adamantine luster on clear faces
Fire
Minimal dispersion visible due to lack of standard facet angles
Scintillation
Low to moderate flashes of light from natural crystal faces and internal cleavage planes
Proportions
Natural rough stone geometry, not faceted
Symmetry
Natural crystal symmetry with octahedral and growth features visible
Polish
Natural crystal faces (trigons and striations), no artificial polish
Fluorescence
Cannot be determined accurately without UV light testing (typically inert to medium blue in natural stones)
Inclusions

Blemishes
Natural surface irregularities, rough edges, and etching features characteristic of rough stones
Origin
Natural origin, likely from alluvial or primary kimberlite deposits (Africa, Russia, or Canada)
Treatment Detection

Estimated Value
Varies widely depending on exact weight, purity, and cutting potential, generally lower per carat for industrial or heavy inclusion grade
