Overall Assessment
An intriguing, high-character natural rough diamond crystal offering versatile potential for custom organic jewelry or precision cutting.
Cut Quality
Not applicable (Rough uncut stone)
Brilliance
Limited in rough form; internal reflections visible through transparent windows
Fire
Minimal dispersion visible due to unpolished curved and natural crystal faces
Scintillation
Low in rough state; will dramatically improve upon cutting and polishing
Proportions
Natural rough proportions, requires professional mapping for optimal cutting yield
Symmetry
Natural distorted octahedral symmetry with characteristic growth lines
Polish
Natural crystal faces (trigons and growth striations visible)
Fluorescence
Cannot be definitively determined without UV testing, likely None to Faint
Inclusions
Natural mineral crystals and internal cloudiness typical of rough diamond formation
Blemishes
Natural surface features, etch channels, and irregular growth markings
Origin
Likely natural alluvial or primary kimberlite pipe origin from an African, Canadian, or Russian source
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Varies significantly based on cutting yield potential, rough diamond market pricing
