Not Applicable (Rough Crystal) Cut
Carat
Estimated 2.0 to 3.5 carats
Color
Near Colorless to Faint Yellow (G-J range estimated)
Clarity
Included (I1-I2 range based on visible internal feathers and clouds)
Shape
Uncut / Raw Octahedral Crystal
Overall Assessment
An interesting, natural rough diamond crystal displaying classic raw growth features. Its final value depends heavily on professional planning for cutting and polishing to optimize yield and clarity.
Cut Quality
Not Applicable (Rough Crystal)
Brilliance
Low (due to rough, unpolished state)
Fire
Minimal (requires facet angles to disperse light effectively)
Scintillation
Poor due to lack of standard faceting
Proportions
Natural crystal habit, no traditional facets
Symmetry
Natural octahedral formation, slightly distorted
Polish
Natural crystalline faces (trigons potentially present)
Fluorescence
Cannot be determined without UV testing (Likely None to Faint)
Inclusions
Internal feathers, crystal inclusions, and cloud clusters visible
Blemishes
Natural surface etch channels and rough skin
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
None detected; untreated natural rough crystal
Estimated Value
$3,000 - $7,000 depending on final yield after cutting and exact clarity
Certification Estimate
GIA or IGI (Rough Diamond Certificate or Origin Report)
Investment Potential
Moderate, highly dependent on the master cutter's ability to maximize yield and polish grade

Setting Suggestions
Raw gemstone organic bezel setting in yellow or white gold to showcase its natural octahedral form
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners while in raw form due to potential trapped inclusions
Interesting Facts
Rough diamonds preserve the geological history of the Earth's mantle where they formed billions of years ago under immense heat and pressure
