Not Applicable (Uncut Rough) Cut
Carat
Estimated 2.50 to 3.50 carats based on visual scale
Color
Near Colorless to Faint Yellow (Estimated G-J range)
Clarity
Included (Estimated I1-I2 due to visible internal fracturing and mineral spots)

Uncut Octahedral / Irregular Crystalline Rough
Overall Assessment
An interesting, unworked natural diamond crystal displaying characteristic surface etching and internal inclusions, best suited for bespoke raw jewelry designs or mineral collections.
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low (characteristic of rough, uncut stones before faceting)
Fire
Minimal dispersion due to lack of standard gemstone faceting
Scintillation
Limited, reflecting light mainly off natural crystal faces rather than internal facets
Proportions
Natural uncut proportions with deep internal crystal structure
Symmetry
Natural Crystalline Symmetry (Distorted Octahedral)
Polish
Raw Natural Crystal Surface (Trigons and etching features typical of rough stones)
Fluorescence
Cannot be definitively determined without UV testing, likely None to Faint
Inclusions
Heavy internal feathers, clouds, and mineral inclusions visible as dark/brown spots
Blemishes
Natural surface roughness, pitting, and oxidation stains
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
None detected; appears entirely untreated and as-mined
Estimated Value
Varies significantly by exact weight and purity, typically valued as industrial or lower-grade gem rough ($300 - $800 USD)
Certification Estimate
GIA or IGI rough diamond report (if certified at origin stage)
Investment Potential
Moderate for collectors of raw minerals, lower for standard gem investment

Raw diamond bezel setting in yellow gold or platinum to preserve its organic, natural state
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush
