Uncut crystal / Rough octahedral form
Overall Assessment
An interesting, natural rough diamond crystal displaying classic octahedral-adjacent growth features, best evaluated by a master cutter before any processing
Cut Quality
Not applicable for rough stone
Brilliance
Low brilliance due to unpolished and rough surfaces
Fire
Minimal dispersion visible through the rough crystal skin
Scintillation
Absent due to lack of faceted surfaces
Proportions
Natural uncut proportions with irregular depth and variable angles
Symmetry
Natural crystal symmetry showing octahedral growth faces
Polish
Raw, unpolished surface with natural crystal skin and trigons
Fluorescence
Unable to determine without UV testing
Inclusions
Cloudy patches, micro-fractures, and potential internal carbon spots
Blemishes
Natural surface etch channels, growth lines, and rough skin
Origin
Likely alluvial or primary pipe deposit natural rough
Treatment Detection
No treatments detected; appears completely untreated and natural
Estimated Value
Varies widely based on internal quality upon cutting, rough estimate $1,000 - $3,500
Certification Estimate
GIA or similar major lab if submitted for rough evaluation
Investment Potential
Moderate, primarily valued as a mineral specimen or for custom cutting potential

Setting Suggestions
Best kept as a collector specimen in a raw wire-wrapped or bezel setting
Care & Maintenance
Store separately to prevent scratching other stones; avoid harsh chemicals and ultrasonic cleaning on included rough
Interesting Facts
Rough diamonds retain their natural geological journey, often showing growth features like triangular etch marks called trigons
