Natural rough diamond crystal
Natural rough diamond crystal · Rough uncut crystal form
Not applicable (uncut rough specimen) Cut
Carat
Estimated 8-12 carats based on visual scale
Color
Near-colorless to faint brown tint (approx. G-I range)
Clarity
Included rough crystal (approx. SI1-SI2 equivalent when cut)
Shape
Rough uncut crystal form
Overall Assessment
A substantial natural rough diamond specimen offering good potential for a skilled cutter to maximize carat weight and clarity through careful planning and sawing.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low in rough state, will exhibit high brilliance once properly faceted
Fire
Muted in current uncut state, highly dependent on future pavilion angles
Scintillation
Absent in rough form; dependent on future cut proportions
Proportions
Natural rough morphology, requires custom blocking and sawing
Symmetry
Natural octahedral/irregular growth symmetry
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Cannot be determined accurately without UV testing, likely None to Faint
Inclusions
Internal cleavage planes, feathers, and potential pinpoint inclusions visible within
Blemishes
Natural surface etchings, striations, and indented natural surfaces
Origin
Alluvial or primary kimberlite pipe deposit, typical of African or Canadian rough diamond sources
Treatment Detection
No evidence of artificial treatments; entirely natural rough stone
Estimated Value
Varies significantly based on cutting yield and final polished color/clarity, rough value typically lower than polished equivalent
Certification Estimate
GIA or similar major lab upon cutting and polishing
Investment Potential
High speculative value depending on final polished yield and grading results after cutting
Similar Diamonds
Comparable to standard run-of-mine natural industrial to near-gem quality rough stones of similar size
Setting Suggestions
Requires professional evaluation for optimal cutting direction before any jewelry setting; can be mounted raw in organic artisan settings
Care & Maintenance
Store separately to prevent scratching other materials; clean gently with warm soapy water and soft brush
Interesting Facts
Displays natural growth lines (striations) and typical irregular crystal habit characteristic of unworked diamond rough
