Overall Assessment
An interesting and authentic natural rough diamond crystal displaying characteristic surface textures and internal inclusions, well-suited for a collector of raw minerals or a custom organic jewelry design after professional evaluation
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low to moderate due to rough surface and natural irregularities
Fire
Minimal, obstructed by rough exterior and inclusions
Scintillation
Limited, reflecting light off raw crystal planes rather than precision facets
Proportions
Natural uncut crystal proportions, irregular depth and length
Symmetry
Natural rough crystal asymmetry
Polish
Unpolished natural crystal faces and fracture surfaces
Fluorescence
Cannot be determined accurately without UV testing, likely Faint to Medium
Inclusions
Visible internal crystal inclusions, dark mineral specks, and internal feather fractures
Blemishes
Natural surface etchings, trigons, and rough fracture marks from extraction
Origin
Alluvial deposit or primary kimberlitic source
Treatment Detection
None detected, appears completely natural and untreated
Estimated Value
Depends heavily on cutting yield, rough market value typically $100 - $400 USD
Certification Estimate
GIA or local gemological lab for rough origin verification
Investment Potential
Low as raw gemstone; value primarily lies in custom lapidary cutting yield or collector value

Setting Suggestions
Raw uncut diamond jewelry, organic gold bezel setting to preserve the natural crystal form
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh chemicals and hard impacts that could exploit natural fracture lines
Interesting Facts
Rough diamonds show natural crystal growth marks such as triangular etchings called trigons on their octahedral faces
