Color
Near Colorless to Faint Yellow (Estimated G-J range)

Included (Estimated SI2-I1 range based on visible internal features and surface irregularities)
Shape
Rough / Uncut Crystal (Octahedral or Irregular Crystal Habit)
Overall Assessment
An interesting, natural rough diamond crystal displaying classic octahedral and distorted growth features, offering potential for custom raw jewelry design or traditional faceting
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Low to Moderate due to rough, unpolished surface and natural coating
Fire
Obscured by rough surface texture
Scintillation
Limited due to lack of standard facets and polish
Proportions
Not Applicable (Rough crystal form with natural faceting)
Symmetry
Natural crystal symmetry showing typical octahedral growth lines and trigons
Polish
Natural unpolished crystal faces (terrace-like growth layers)
Fluorescence
Undetermined visually (Requires UV testing)
Inclusions
Visible internal inclusions, feather fractures, and potential crystal spots
Blemishes
Natural surface roughness, adhering matrix/dirt, and pitting on crystal faces
Origin
Alluvial or primary kimberlite deposit (African or Canadian origin likely)
Treatment Detection
No treatments detected; completely natural rough specimen
Estimated Value
Varies widely depending on yield after cutting, estimated rough value $500 - $1,500 USD
Certification Estimate
GIA or EGL (upon cutting and polishing, would likely receive standard commercial grading)
Investment Potential
Moderate; value depends heavily on the master cutter's skill to maximize yield and clarity if faceted

Setting Suggestions
Can be custom-set in its raw state in a protective bezel setting (organic/raw jewelry style), or cut into a brilliant round or cushion shape
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh chemicals and impact on cleavage planes
Interesting Facts
The specimen exhibits natural growth lines and stepped faces characteristic of diamond crystallization under high pressure and temperature deep within the Earth's mantle
