Overall Assessment
An intriguing natural rough diamond crystal displaying classic growth features, well-suited for a specialized raw-stone jewelry design or mineral collection
Cut Quality
Not applicable (Rough crystal, uncut state)
Brilliance
Varies due to rough unpolished state, exhibits vitreous to adamantine luster on crystal faces
Fire
Limited dispersion due to lack of faceted optical geometry, confined to natural windowing areas
Scintillation
Low to moderate flash effect from unpolished natural facets and internal reflections
Proportions
Elongated crystal habit, typical of natural alluvial or primary deposit rough
Symmetry
Natural crystal symmetry, distorted octahedral growth habit
Polish
Natural crystal faces (trigons and striations visible on surface)
Fluorescence
Cannot be definitively determined without UV testing, likely None to Faint
Inclusions
Internal cleavage planes, feathers, and potential cloud formations visible
Blemishes
Natural surface etching, trigons, and irregular growth features
Origin
Likely natural primary kimberlitic or secondary alluvial origin (Africa, Canada, or Russia)
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Varies widely depending on cutting yield, approximately $500 - $1,500 USD for the rough specimen
Certification Estimate
GIA or specialized rough grading services (e.g., De Beers rough evaluation)
Investment Potential
Moderate to high as a unique collector's specimen or custom bespoke investment piece
