Carat
Estimated 1.5 to 2.5 carats based on visual scale
Color
Near-colorless to faint yellow tint (approx. G-J range)
Clarity
Included (approx. SI2-I1 range due to visible natural surface features and internal characteristics)
Shape
Rough crystal / Irregular uncut form
Overall Assessment
An interesting, natural rough diamond crystal displaying characteristic growth lines and surface texture, offering high potential if custom-faceted by an expert lapidary
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Limited due to rough surface texture, will exhibit high brilliance once cut and polished
Fire
Present in localized transparent windows
Scintillation
Minimal in current rough state
Proportions
Natural rough proportions, requires professional mapping for optimal cutting potential
Symmetry
Natural asymmetrical crystal growth formation
Polish
Natural crystal faces (trigons and growth lines visible)
Fluorescence
Indeterminate from visual inspection alone (typically tested via UV light)
Inclusions
Internal feather fractures and mineral inclusions likely present
Blemishes
Natural surface pitting, rough skin, and possible cavities
Origin
Alluvial or primary kimberlite pipe deposit origin (exact mine location unknown without advanced testing)
Treatment Detection
No treatments detected; appears entirely untreated and natural
Estimated Value
Varies significantly based on final cut yield, roughly $1,000 to $3,000 USD for rough stone
Certification Estimate
GIA or IGI rough diamond evaluation report recommended
Investment Potential
Moderate, primarily holds value as a collector's mineral specimen or raw jewelry piece
Similar Diamonds
Comparable to standard run-of-mine industrial or lower-tier commercial rough diamond crystals
Setting Suggestions
Can be custom-set raw in an organic bezel setting, or professionally cut and polished into a traditional brilliant shape for a standard setting
Care & Maintenance
Store separately to avoid scratching other gems; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain the natural geometric growth patterns (often octahedral or dodecahedral) formed deep within the Earth's mantle over billions of years
