Overall Assessment
An interesting and substantial natural rough diamond specimen with visible crystal features, suitable either as a collector's mineral specimen or for professional cutting and polishing
Cut Quality
Not applicable (Rough, unpolished crystal specimen)
Brilliance
Low in rough form, increases significantly once cut and polished
Fire
Minimal in rough state due to lack of standard facet angles
Scintillation
Limited flash effect on raw crystal faces
Proportions
N/A for rough crystal
Symmetry
Natural asymmetrical crystal growth
Polish
Raw natural crystal faces, possibly showing some natural octahedral or irregular strictions
Fluorescence
Unknown without UV testing (typically inert to medium blue in natural rough)
Inclusions
Heavy internal feathering, cloudiness, and crystal inclusions visible
Blemishes
Natural surface etch channels, trigons, and surface pitting typical of rough diamonds
Origin
Likely alluvial or primary kimberlite pipe origin from an established diamond-producing region (e.g., Africa, Canada, Russia, or Australia)
Treatment Detection
No signs of artificial treatment; appears completely untreated and natural
Estimated Value
Varies widely depending on internal purity, recovery yield after cutting, and exact weight; rough diamonds of this size can range from a few hundred to thousands of dollars
Certification Estimate
GIA or similar major gemological lab would grade this as unmounted rough if requested, typically certified after cutting
Investment Potential
Raw specimens hold collectible and intrinsic value, though polished stones generally offer more liquid market potential
