Natural (Rough Crystal/Fragment)
Natural (Rough Crystal/Fragment) · Irregular / Raw Cresent-like Fragment
Not Applicable (Uncut Rough Specimen) Cut
Carat
Estimated 4.5 - 6.0 carats based on relative finger size comparison
Color
Estimated H-J range (near colorless with subtle warm undertones)
Clarity
Estimated SI1 - SI2 (contains natural internal cloudiness and localized feather features)
Shape
Irregular / Raw Cresent-like Fragment
Overall Assessment
An intriguing, sizable natural rough diamond fragment exhibiting fascinating natural wear patterns, offering great potential for custom lapidary cutting
Cut Quality
Not Applicable (Uncut Rough Specimen)
Brilliance
Low due to lack of faceting and matte/etched surface texture
Fire
Minimal dispersion visible primarily through translucent edges
Scintillation
Absent due to lack of faceted surfaces
Proportions
Not Applicable (Uncut Rough Specimen)
Symmetry
Natural asymmetric form typical of alluvial or weathered rough stones
Polish
Raw natural surface with typical glacial or water-worn frosting and natural etch channels
Fluorescence
Cannot be definitively determined without UV testing, likely Faint to Medium Blue
Inclusions
Cloud-like clusters, internal tension cracks, and minute mineral crystals visible under magnification
Blemishes
Natural surface pitting, trigons (growth marks), and abrasion marks from alluvial transport
Origin
Likely Alluvial African or South American deposit due to the smooth water-worn contours
Treatment Detection
No evidence of artificial enhancement; completely untreated natural rough
Estimated Value
Varies significantly based on cutting potential, roughly $500 - $1,500 USD for rough specimen value
Certification Estimate
GIA or HRD (Rough Gemstone Verification Certificate)
Investment Potential
Moderate speculative value depending on how much weight can be retained during custom cutting
Similar Diamonds
Comparable alluvial rough stones from artisanal mining operations in West Africa
Setting Suggestions
Requires professional cutting and faceting into custom shapes before jewelry setting (e.g., custom pendant in yellow gold)
Care & Maintenance
Store securely in a padded gem jar to prevent chipping along natural cleavage planes
Interesting Facts
The crescent-like shape is an unusual natural sculptural form resulting from asymmetric dissolution and natural wear in an alluvial river bed
