Included (Estimated I1 due to heavy internal fractures and structural flaws)
Shape
Rough crystal / Uncut octahedral habit
Overall Assessment
This is a raw, uncut natural diamond crystal showing characteristic cleavage planes, growth lines, and internal fracturing. While lacking the optical performance of a faceted diamond, it is a fascinating geological specimen in its natural rough state.
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low due to lack of standard diamond faceting and presence of internal fracturing
Fire
Limited dispersion visible internally through natural fracture planes
Scintillation
Minimal, localized flashes from cleavage planes rather than facet returns
Proportions
Natural crystal proportions, un-faceted
Symmetry
Natural octahedral symmetry distorted by growth and cleavage lines
Polish
Natural crystal faces showing growth lines (trigons or striations)
Fluorescence
Cannot be definitively determined without UV testing, likely Faint to Medium
Inclusions
Multiple internal feather fractures, cleavages, and potential mineral inclusions
Blemishes
Natural surface etch channels, growth marks, and minor abrasions
Origin
Natural alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; completely natural state
Estimated Value
Valued primarily as a mineral specimen or industrial/low-grade gem rough ($500 - $1,500 depending on exact weight and purity)
Certification Estimate
GIA or AGS if polished, though rough evaluation reports can be issued
Investment Potential
Low investment potential for standard resale; higher collectible value as a raw mineral specimen

Setting Suggestions
Wire-wrapped pendant setting or custom organic prong setting to preserve its raw crystal form
Care & Maintenance
Store separately to prevent scratching other materials; avoid harsh ultrasonic cleaners due to internal fracturing
Interesting Facts
Displays natural growth striations on the crystal face characteristic of natural diamond formation deep within the Earth's mantle
