Overall Assessment
An intriguing, natural rough diamond crystal displaying classic octahedral-related growth features, offering immense potential for a custom-cut faceted gemstone or preservation as a collector's raw mineral specimen.
Cut Quality
Not applicable (uncut rough stone)
Brilliance
Low to moderate due to rough unpolished surface scattering light
Fire
Limited surface dispersion due to lack of faceted geometry
Scintillation
Minimal sparkle; reflects light diffusely off natural crystal planes
Proportions
Natural crystal proportions, depth and table percentages do not apply
Symmetry
Natural distorted octahedral symmetry
Polish
None (natural crystal faces showing growth lines and trigons)
Fluorescence
Indeterminate from visual assessment alone, likely none to faint
Inclusions
Natural internal crystal inclusions and feather fractures typical of rough diamonds
Blemishes
Natural surface etchings, striations, and irregular growth features
Origin
Likely alluvial or primary kimberlite deposit from African, Canadian, or Russian origin
Treatment Detection
No signs of artificial treatment; completely natural rough specimen
Estimated Value
Varies widely based on cutting yield potential, roughly $1,000 to $3,500 depending on final polished recovery
Certification Estimate
GIA Rough Diamond Evaluation or Kimberley Process certification
Investment Potential
Moderate, highly dependent on the skill of the master cutter if faceted, or valued as a unique collector specimen

Setting Suggestions
Best preserved as a raw mineral specimen, or custom-designed in an organic raw diamond bezel setting using yellow gold or platinum
Care & Maintenance
Store separately to prevent scratching other stones, clean with mild soapy water and a soft brush
Interesting Facts
Displays natural crystal growth lines and striations directly as formed deep within the Earth's mantle over billions of years
