Overall Assessment
An interesting raw diamond crystal fragment showcasing natural geological features, primarily suited for mineral collectors or custom organic jewelry rather than standard cut-and-polished gemstone markets.
Cut Quality
Not applicable (Rough crystal)
Brilliance
Low due to lack of standard faceting and heavy internal fracturing
Fire
Minimal dispersion visible through raw windows
Scintillation
Poor, localized flash effects from internal fracture planes
Proportions
Elongated tabular rough stone
Symmetry
Natural asymmetric crystal growth
Polish
Raw natural crystal faces with conchoidal fracture surfaces
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Heavy internal fracturing, cleavage planes, and cloud-like inclusions
Blemishes
Natural surface etching, trigons, and rough fracture edges
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
No visible evidence of artificial treatments
Estimated Value
Low-to-moderate specimen value ($50 - $200 USD depending on exact weight and purity)
Certification Estimate
Not standard for industrial rough; would require specialized gemological laboratory report (e.g., GIA rough report)
Investment Potential
Minimal investment value as a diamond; valued primarily as a raw mineral specimen or educational piece
Similar Diamonds

Setting Suggestions
Wire-wrapped pendant, organic rustic bezel setting, or kept as a raw mineral specimen
Care & Maintenance
Store separately to prevent scratching other stones; clean with warm soapy water and a soft brush
