Not applicable (uncut rough mineral specimen) Cut
Carat
Estimated 0.50 - 0.85 carats based on visual scale relative to matrix
Color
Near colorless to faint brown tint (approx. G-I range)
Clarity
Included (approx. SI1-SI2 range with natural internal feathers and crystal inclusions)
Shape
Uncut rough octahedral or modified crystal habit
Overall Assessment
This is an authentic, untreated natural rough diamond crystal embedded within its host rock matrix, presenting a fascinating specimen for collectors and geology enthusiasts rather than a finished faceted gem.
Cut Quality
Not applicable (uncut rough mineral specimen)
Brilliance
Subdued due to unpolished rough surfaces and matrix enclosure
Fire
Limited dispersion visible through raw translucent crystal windows
Scintillation
Minimal sparkle; reflects light diffusely off natural crystal faces
Proportions
Natural rough proportions, uncut crystal morphology
Symmetry
Natural crystallographic symmetry showing octahedral growth lines
Polish
Natural crystal face texture (trigons and striations visible)
Fluorescence
Indeterminate from visual observation alone (requires UV testing)
Inclusions
Internal mineral inclusions and cleavage planes visible within the translucent crystal
Blemishes
Natural surface etch channels, growth marks, and contact marks from host rock
Origin
Natural primary deposit (kimberlite or alluvial secondary deposit)
Treatment Detection
None detected; entirely untreated raw mineral specimen
Estimated Value
Varies widely as a mineral specimen; lower intrinsic polished gem value due to raw state
Certification Estimate
GIA or local gemological institute report for rough diamond verification
Investment Potential
Valued more as a unique geological collector's specimen than liquid diamond investment
Similar Diamonds
Other alluvial rough diamond crystals from artisanal mining regions
Setting Suggestions
Wire-wrapped raw mineral pendant or bespoke bezel setting to preserve natural crystal form
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural geological history, often preserving crystal growth markers like trigons formed millions of years ago deep within the Earth's mantle.
