Overall Assessment
An interesting, sizable natural rough diamond crystal displaying classic growth characteristics and promising good potential for faceted yield.
Cut Quality
Not applicable (uncut rough stone)
Brilliance
Low in rough state, will be maximized upon cutting
Fire
Subdued in rough state, high potential upon faceted finishing
Scintillation
Minimal in raw state
Proportions
Natural rough proportions, awaiting lapidary planning
Symmetry
Natural crystalline symmetry
Polish
Natural crystal faces with typical growth lines (trigons)
Fluorescence
Cannot be determined without UV testing, likely None to Faint
Inclusions
Internal mineral crystals and feathers typical of rough stones
Blemishes
Natural surface etch channels, growth features, and potential indentation
Origin
Natural geological origin from a primary kimberlite pipe or secondary alluvial deposit
Treatment Detection
No visible signs of artificial enhancement or treatment
Estimated Value
Variable depending on final cut yield, roughly $1,500 to $4,000 USD
Certification Estimate
GIA or similar major laboratory would grade post-cutting
Investment Potential
Moderate, highly dependent on the precision of the final cut and polish
