Overall Assessment
This is an appealing, natural rough diamond specimen with significant inclusions and a raw, unpolished exterior, best suited for mineral collections or unique organic-style jewelry rather than high-end cutting.
Cut Quality
Not Applicable (Rough stone)
Brilliance
Low due to rough, unpolished state and internal cloudiness
Fire
Minimal due to uncut nature and surface irregularities
Scintillation
Poor, as it lacks faceted angles to reflect moving light
Proportions
Uncut crystal rough, proportions do not apply
Symmetry
Natural irregular symmetry
Polish
Raw natural crystal surface with wet appearance
Fluorescence
Cannot be determined without UV testing, likely Faint to Medium Blue
Inclusions
Heavy internal feathering, clouding, and dark mineral inclusion pockets
Blemishes
Natural surface pitting, rough skin, and textural flaws
Origin
Likely alluvial deposit origin (river or stream bed)
Treatment Detection
No signs of artificial enhancement; completely untreated natural rough
Estimated Value
$100 - $300 as a rough specimen or collector's rough piece
Certification Estimate
Gemological laboratories would grade this as industrial or low-tier ornamental rough; GIA does not issue standard reports for unpolished rough stones
Investment Potential
Low investment value as gem material; primarily of interest to mineral collectors
Similar Diamonds
Standard industrial-grade or low-gem-quality alluvial rough diamonds
Setting Suggestions
Wire-wrapped pendant setting or custom organic prong setting to preserve its raw aesthetic
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh chemicals and impact on fracture lines
Interesting Facts
Rough diamonds often have a greasy luster and water-worn exterior when recovered from alluvial deposits
