Natural rough diamond crystal embedded in matrix
Natural rough diamond crystal embedded in matrix · Rough crystal / Irregular octahedral fragment
Not Applicable (Uncut rough specimen) Cut

Carat
Estimated 2.50 - 3.50 carats in rough state
Color
Near-colorless to light brown tint (approx. J-K range)
Clarity
Included (I1 - I2 due to internal feathers and crystal inclusions)
Shape
Rough crystal / Irregular octahedral fragment
Overall Assessment
An interesting and authentic natural rough diamond specimen exhibiting classic crystal morphology and surface textures, offering potential for lapidary work or raw jewelry design
Cut Quality
Not Applicable (Uncut rough specimen)
Brilliance
Low in rough state; will increase significantly upon cutting and faceting
Fire
Obscured by rough surface texture; potential is present once faceted
Scintillation
Minimal play of light on rough faces; will be established upon proper pavilion and crown cutting
Proportions
Natural crystal habit; non-standard proportions
Symmetry
Natural octahedral symmetry distorted by growth patterns
Polish
Natural unpolished crystal faces (trigons and striations visible)
Fluorescence
Unable to determine without UV testing (Likely Faint to Medium Blue)
Inclusions
Internal feathers, carbon spots, and cloud formations visible within the rough
Blemishes
Natural surface fractures, pitting, and adhering matrix material
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
None detected; completely untreated natural rough stone
Estimated Value
$1,500 - $3,500 USD depending on final cutting yield and clarity retention
Certification Estimate
GIA or EGL for rough evaluation and subsequent polished report
Investment Potential
Moderate, primarily as a collector's mineral specimen or speculative raw material for custom cutting
Similar Diamonds
Comparable to standard industrial-to-near-gem grade run-of-mine African rough diamonds
Setting Suggestions
Can be set in its raw, uncut form in a bespoke organic bezel setting, or faceted into a cushion or round brilliant shape
Care & Maintenance
Avoid harsh acids and ultrasonic cleaners while in rough matrix form; store separately to prevent scratching other gemstones
Interesting Facts
Rough diamonds display natural triangular growth marks called trigons on their crystal faces, formed millions of years ago deep within the Earth's mantle
