Natural rough diamond
Natural rough diamond · Rough uncut octahedral/irregular crystal
Not applicable (uncut rough stone) Cut
Carat
Estimated 3.50 carats based on visual size
Color
Near colorless to light yellow tint (approx. K-M range)
Clarity
I3 due to extensive internal fracturing and dark mineral inclusions
Shape
Rough uncut octahedral/irregular crystal
Overall Assessment
This is a raw, natural diamond crystal containing significant structural inclusions and internal fractures, highly suitable as a geological specimen rather than for fine jewelry.
Cut Quality
Not applicable (uncut rough stone)
Brilliance
Low brilliance due to opacity, fracturing, and lack of polished facets
Fire
Minimal fire observable in its current uncut state
Scintillation
Negligible scintillation; light does not properly reflect internally
Proportions
Natural rough proportions, unmanipulated by cutting
Symmetry
Natural distorted crystal symmetry
Polish
Natural unpolished crystal faces with typical trigons/growth lines
Fluorescence
Unable to determine without UV testing (likely Faint to Medium Blue)
Inclusions
Heavy internal feather fractures, dark carbon/graphite spots, and cloudiness
Blemishes
Natural surface etch channels, pits, and rough skin textures
Origin
Natural primary alluvial or pipe deposit origin (African or Canadian rough)
Treatment Detection
No evidence of artificial treatments; entirely natural rough stone
Estimated Value
Low commercial/industrial value due to high inclusion count
Certification Estimate
GIA or similar major lab, noting heavy inclusions and rough state
Investment Potential
Low investment potential for jewelry use; primarily of mineralogical or collector interest
Similar Diamonds
Other low-grade industrial or mineral-specimen rough diamonds
Setting Suggestions
Best left in its organic, natural rough state as a collector piece or specimen
Care & Maintenance
Store carefully to avoid catching on fracture lines; clean gently with warm soapy water
Interesting Facts
Rough diamonds showcase the natural growth habits of carbon under extreme mantle pressure
