Overall Assessment
An intriguing natural rough diamond crystal showing authentic geological features, growth lines, and inclusions, offering good potential for a custom-cut faceted gemstone.
Cut Quality
Not Applicable (Rough Stone)
Brilliance
Low due to rough, unpolished surfaces and internal inclusions
Fire
Minimal dispersion visible in current rough state
Scintillation
Poor in current state; will improve significantly upon cutting and polishing
Proportions
Irregular rough crystal proportions; depth and table percentages do not apply
Symmetry
Asymmetrical (Natural crystal formation)
Polish
Natural crystalline surface with growth lines and etching features
Fluorescence
Cannot be definitively determined without UV testing, likely Faint to Medium
Inclusions
Visible dark mineral inclusions, internal feather fractures, and cloudiness
Blemishes
Natural surface trigons, growth lines, surface pits, and adhering matrix material
Origin
Alluvial or primary kimberlite deposit origin
Treatment Detection
No visible signs of artificial treatments; completely untreated natural rough
Estimated Value
Variable based on cutting yield, approximately $1,500 to $3,500 USD in rough form
Certification Estimate
GIA or HRD would issue a rough diamond report or diamond grading report post-cut
Investment Potential
Moderate; value heavily depends on the skill of the lapidary cutting the rough to maximize yield and final clarity

Setting Suggestions
Can be custom-set raw in an organic bezel setting or cut and polished into a modern brilliant or fancy shape for traditional settings
Care & Maintenance
Store separately to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
