Natural rough diamond
Natural rough diamond · Rough crystal / Irregular octahedral fragment
Uncut rough, not applicable Cut
Carat
Estimated 1.5 to 2.5 carats based on visual proportions
Color
Near-colorless to faint yellow/brown tint (approx. K-M equivalent)
Clarity
Included (I1-I3) due to heavy natural internal inclusions and cloudiness
Shape
Rough crystal / Irregular octahedral fragment
Overall Assessment
An interesting, natural uncut diamond crystal fragment displaying characteristic rough features, heavy internal inclusions, and natural surface textures, ideal for mineral collectors or custom lapidary work
Cut Quality
Uncut rough, not applicable
Brilliance
Minimal, as the stone is uncut and translucent rather than transparent and faceted
Fire
Very low to none due to lack of standard facet geometry
Scintillation
Absent due to rough unpolished state
Proportions
Natural crystal habit, no traditional table, depth, or angles
Symmetry
Natural asymmetrical rough formation
Polish
Unpolished natural crystal faces with some etched or frosted features
Fluorescence
Cannot be reliably determined without UV light testing, likely Faint to Medium
Inclusions
Significant internal cloudiness, feather fractures, and potential mineral inclusions (such as dark spots visible near the edge)
Blemishes
Natural growth marks, trinitets, or surface pitting typical of rough crystals
Origin
Natural alluvial or primary kimberlite deposit origin
Treatment Detection
No obvious signs of artificial treatment; appears entirely natural and untreated
Estimated Value
Modest commercial value as a specimen or industrial/low-tier gem-grade rough (approx. $100 - $300 USD)
Certification Estimate
GIA or IGI rough diamond report if submitted
Investment Potential
Low investment potential for resale, primarily valued as a collector mineral specimen or educational piece

Setting Suggestions
Best preserved as a raw specimen crystal in a bespoke organic bezel setting, or cut and polished into a custom faceted gem
Care & Maintenance
Store separately to avoid scratching other jewelry, clean with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural geological history, showing how carbon crystallizes deep within the Earth's mantle over billions of years before being brought to the surface
