Natural rough diamond crystal
Natural rough diamond crystal · Uncut octahedral or elongated crystal rough
Not applicable (uncut rough specimen) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual scale against fingers
Color
Near-colorless to light brown tinted (approx. K-M range)
Clarity
I1 to I3 (Included rough with notable surface markings and internal inclusions)
Shape
Uncut octahedral or elongated crystal rough
Overall Assessment
An authentic natural rough diamond crystal displaying characteristic surface etchings and internal inclusions, typical of unworked mine-run material.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Limited to none in current rough state due to unpolished faces
Fire
Minimal visible fire prior to cutting and faceting
Scintillation
Not applicable for rough crystal
Proportions
Natural rough crystal proportions, elongated habit
Symmetry
Natural crystal symmetry showing octahedral growth lines and striations
Polish
Natural crystal faces (trigons and etched surface features)
Fluorescence
Indeterminate from visual inspection (likely None to Faint)
Inclusions
Heavy internal clouding, dark mineral inclusions, and feather fractures
Blemishes
Natural surface pitting, etch channels, and rough skin
Origin
Alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Low to moderate as a mineral specimen; value depends heavily on potential yield if cut
Certification Estimate
GIA or EGL, likely graded as industrial or lower-tier commercial quality rough
Investment Potential
Low investment potential for jewellery, primarily of interest to mineral collectors
Similar Diamonds
Typical run-of-mine industrial or lower commercial grade rough diamond crystals
Setting Suggestions
Best preserved as a raw mineral specimen in a wire-wrap or organic bezel setting
Care & Maintenance
Store carefully to avoid chipping along natural cleavage planes
Interesting Facts
The surface features often show distinct growth markings like triangular depressions called trigons
