Overall Assessment
This is a fascinating specimen of a natural, uncut rough diamond showing characteristic alluvial wear and prominent internal inclusions. While unsuitable for traditional faceted jewelry, it possesses a raw, organic charm ideal for bespoke artisan jewelry or mineral collections.
Cut Quality
Not Applicable (Uncut rough stone)
Brilliance
Low, due to lack of facets and numerous internal inclusions
Fire
Minimal, obstructed by inclusions and lack of standard cut proportions
Scintillation
Poor, lacking facets to reflect and bounce light dynamically
Proportions
Not Applicable for rough stones
Symmetry
Natural asymmetrical rough form
Polish
Natural unpolished surface, slightly weathered or etched
Fluorescence
Cannot be determined without UV light testing (Likely None to Faint)
Inclusions
Heavy mineral inclusions, dark carbon spots, iron staining, and internal feather fractures
Blemishes
Natural surface pits, rough spots, and minor abrasion marks from alluvial transport
Origin
Likely alluvial deposit (river or coastal secondary deposit) due to the rounded, water-worn shape
Treatment Detection
No treatments detected; completely natural untreated rough
Estimated Value
Nominal mineral specimen value ($20 - $100 USD depending on exact weight and origin)
Certification Estimate
Typically not certified by major labs (GIA/AGS) in this raw, heavily included state; would receive a basic gemological identification report if requested
Investment Potential
Low investment potential for jewelry use; primarily valued as a raw geological specimen or curiosity
Similar Diamonds
Industrial grade or low-quality gem-grade alluvial rough diamonds
Setting Suggestions
Best suited for organic wire-wrapped jewelry, custom raw stone bezel settings, or kept as a mineral specimen
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh chemicals or ultrasonic cleaners due to internal fractures
Interesting Facts
Most gem diamonds are found in secondary alluvial deposits where rivers have transported them far from their primary kimberlite pipe origins, resulting in smoothed, rounded pebbles like this one
