Natural rough crystal
Natural rough crystal · Uncut octahedral or irregular crystal habit
Not applicable (rough, uncut crystal specimen) Cut
Carat
Estimated 3.50 to 5.00 carats in rough state
Color
Near-colorless to faint yellow (approximate G-I range)
Clarity
Included (I1-I2 range) due to visible surface and internal features
Shape
Uncut octahedral or irregular crystal habit
Overall Assessment
An intriguing natural diamond crystal specimen showing characteristic rough texture, suitable either for specialized mineral collection or precision cutting into a faceted gemstone.
Cut Quality
Not applicable (rough, uncut crystal specimen)
Brilliance
Low in rough form; will improve significantly upon cutting and polishing
Fire
Subdued in rough state; dependent on final cut proportions
Scintillation
Minimal in rough form due to unpolished surfaces
Proportions
Natural rough proportions, requires expert planning for cutting
Symmetry
Natural crystal symmetry, distorted octahedral or irregular growth
Polish
Natural crystal faces (trigons and striations expected)
Fluorescence
Cannot be reliably determined from visual appearance alone, likely None to Faint
Inclusions
Internal carbon spots, feathers, and cloud inclusions visible
Blemishes
Natural surface etch channels, pits, and adhering matrix material
Origin
Likely alluvial or primary kimberlite deposit origin (African or Canadian source)
Treatment Detection
No treatments detected; completely untreated natural rough
Estimated Value
Varies widely based on yield after cutting, rough value approximately $500 - $1,500 depending on final cut weight and clarity retention
Certification Estimate
GIA or IGI rough diamond report if submitted
Investment Potential
Moderate, primarily holds value as a collector mineral specimen or speculative cutting rough
Similar Diamonds
Comparable to standard industrial-to-gem grade natural rough parcels
Setting Suggestions
Can be set raw in a custom organic or rustic bezel setting, or cut into a cushion or emerald shape for a traditional mounting
Care & Maintenance
Clean with warm soapy water and a soft brush; protect from hard impacts which can cleave along natural planes
