Rough natural diamond specimen (uncut crystal)
Rough natural diamond specimen (uncut crystal) · Irregular octahedron/dodecahedron crystal habit
Not applicable (uncut rough stone) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual scale
Color
Near-colorless to faint yellow tint (approx. G-J range)
Clarity
Included (I1-I3) due to internal feather fractures and clouds visible in the rough
Shape
Irregular octahedron/dodecahedron crystal habit
Overall Assessment
An authentic, raw diamond crystal displaying natural geological formation features, high hardness, and potential for custom lapidary work or mineral collection
Cut Quality
Not applicable (uncut rough stone)
Brilliance
Limited in rough form; exhibits vitreous to adamantine luster on raw faces
Fire
Minimal dispersion visible due to lack of faceted cut angles
Scintillation
Absent due to unpolished and uncut state
Proportions
Natural rough proportions, deep non-standard geometry
Symmetry
Natural crystal symmetry showing distorted growth lines
Polish
Natural crystalline faces (trigons and striations visible)
Fluorescence
Cannot be determined without UV light testing (typically Medium Blue in many rough stones)
Inclusions
Prominent internal feathers, clouds, and needle-like inclusions
Blemishes
Natural surface pitting, rough skin, and irregular resorption faces
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
No treatments detected; entirely untreated natural rough mineral
Estimated Value
Depends heavily on yield after cutting, roughly $1,500 to $3,500 USD for rough state
Certification Estimate
GIA or IGI rough diamond report / Kimberley Process origin verification
Investment Potential
Moderate, primarily valued as a collector mineral specimen or speculative cutting rough
Similar Diamonds
Comparable to standard industrial-to-near-gem quality run-of-mine rough diamond crystals
Setting Suggestions
Best preserved as a raw mineral specimen in a custom organic bezel setting, or cut into a custom shape
Care & Maintenance
Store separately to prevent scratching other materials; clean gently with warm soapy water and a soft brush
Interesting Facts
This specimen demonstrates natural crystal growth steps, striations, and octahedral habit straight from the earth before human intervention
