Overall Assessment
This is a raw, unpolished natural diamond or crystalline quartz mineral specimen showing heavy internal inclusions, natural surface etching, and a brownish-grey hue typical of industrial or low-gem quality rough stones.
Cut Quality
Not applicable (Rough stone)
Brilliance
Very low to none (opaque/translucent rough surface)
Fire
Absent in current rough state
Scintillation
Minimal to none due to lack of facets and transparency
Proportions
Irregular raw crystal proportions, high depth percentage
Symmetry
Natural asymmetrical crystal growth
Polish
Raw, unpolished matrix surface with natural crystal faces and etching
Fluorescence
Cannot be determined without UV testing (likely inert to faint blue)
Inclusions
Numerous internal feathers, fractures, cloud clusters, and dark mineral inclusions
Blemishes
Natural surface pitting, trigons, and etching marks
Origin
Alluvial deposit or primary kimberlite pipe (Africa, Australia, or Arkansas state park origin likely)
Treatment Detection
No treatments detected; completely natural untreated rough
Estimated Value
$50 - $150 USD as a mineral specimen / industrial grade rough
Certification Estimate
Gemological Institute of America (GIA) or local laboratory report for rough identity verification
Investment Potential
Low investment value; sold primarily as a novelty, educational, or mineral specimen piece

Setting Suggestions
Wire-wrapped raw crystal pendant or rustic bezel setting to preserve natural character
Care & Maintenance
Store separately to avoid scratching softer gems; clean with mild soapy water and a soft brush
Interesting Facts
Most mined diamonds are of industrial grade and never become jewelry; rough stones show the natural octahedral crystal habit formed deep in the Earth's mantle.
