Carat
Estimated 1.5 - 2.5 carats
Color
Brownish / Off-Color (Low grade for cutting, likely near J-K or lower, or industrial brown)
Clarity
I3 / Included (Heavy natural inclusions, fractures, and cloudiness)
Shape
Rough Uncut Octahedron / Irregular Crystal
Overall Assessment
An untreated, natural rough diamond crystal of low clarity and dark coloration, suitable as a raw mineral specimen rather than a polished gemstone
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Poor to minimal (due to rough surface and heavy internal inclusions)
Fire
Very low to none in current state
Scintillation
Minimal to none due to lack of faceted surfaces
Proportions
Natural uncut proportions; deep unoptimized rough morphology
Symmetry
Natural crystal symmetry (distorted octahedron/rounded edges)
Polish
Unpolished natural crystal faces (some etched features)
Fluorescence
Indeterminate (Cannot be assessed visually without UV testing)
Inclusions
Heavy internal clouding, feathers, carbon spots, and stress fractures
Blemishes
Natural surface etching, trigons, pitting, and rough skin
Origin
Alluvial or primary kimberlitic deposit (African or Canadian origin likely)
Treatment Detection
No signs of artificial treatment; completely natural rough stone
Estimated Value
Low commercial value (primarily specimen, industrial abrasive, or low-tier cutting material value, estimated under $50 USD)
Certification Estimate
Industrial or uncertified rough lot grading; not viable for standard GIA/AGS luxury grading report
Investment Potential
Low investment potential; useful mainly as a mineral specimen or educational piece

Setting Suggestions
Wire-wrapped organic rough jewelry setting or custom raw mineral prong setting in yellow or rose gold
Care & Maintenance
Handle with care to avoid chipping along natural cleavage planes; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds display natural crystal growth marks called trigons and often require significant weight loss during cutting to yield a clean faceted gem
