Natural Rough Diamond
Natural Rough Diamond · Uncut / Rough Crystalline (Octahedral/Irregular)
Not Applicable (Rough, unpolished crystal) Cut
Carat
Estimated 3.5 - 5.0 carats based on visual dimensions
Color
Near-Colorless to Light Brownish Tint (Estimated G-J range)
Clarity
Included (I1-I3 range for rough), containing internal crystal and cloud inclusions
Shape
Uncut / Rough Crystalline (Octahedral/Irregular)
Overall Assessment
This is an authentic, untreated natural rough diamond crystal featuring visible inclusions and character. While its current clarity and rough state limit its immediate use as a high-end polished gem without substantial weight loss during cutting, it remains a fascinating and genuine geological specimen.
Cut Quality
Not Applicable (Rough, unpolished crystal)
Brilliance
Limited due to rough surface and heavy inclusions
Fire
Minimal visible fire in its raw, uncut state
Scintillation
Low scintillation; light is scattered internally rather than returned uniformly
Proportions
Natural crystal habit, uneven depth and proportions prior to any cutting
Symmetry
Natural crystal growth symmetry showing octahedral faces and trigons
Polish
Natural rough crystal faces (some etched or frosted features)
Fluorescence
Cannot be determined without UV testing (Likely None to Faint)
Inclusions
Heavy internal clouding, dark mineral inclusions (possibly graphite or sulfide), and feathers
Blemishes
Natural surface trigons, pitting, and rough patches from host rock interaction
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin typical)
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Varies widely based on potential cut yield; rough industrial/commercial grade estimated at $500 - $1,500
Certification Estimate
GIA or similar major lab if submitted as a rough parcel or custom report
Investment Potential
Moderate as a collector specimen, but primarily valued as raw material for cutting
Similar Diamonds
Industrial or lower-clarity jewelry-grade rough diamond crystals of similar weight
Setting Suggestions
Can be preserved in an organic raw diamond ring setting (bezel setting in yellow or white gold) or cut down into a brilliant shape
Care & Maintenance
Store separately to avoid scratching other gems; clean with mild soapy water and a soft brush
Interesting Facts
Rough diamonds preserve the natural geological history of the Earth's mantle, often taking billions of years to form under extreme pressure and temperature.
