Rough uncut crystal / Pebble form
Overall Assessment
An interesting and authentic natural rough diamond crystal displaying characteristic surface textures and geological features, best suited for raw jewelry designs or mineral collections.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low to moderate due to rough, unpolished surface inhibiting light entry
Fire
Minimal to none in current rough state
Scintillation
Absent due to lack of faceted surfaces
Proportions
Natural octahedral or irregular crystal habit without standardized proportions
Symmetry
Natural asymmetric crystal growth
Polish
Natural rough surface with characteristic trigons, etching features, and wear
Fluorescence
Cannot be determined without UV testing (estimated None to Faint)
Inclusions
Natural mineral inclusions, feathers, and internal cloudiness typical of rough stones
Blemishes
Natural surface pitting, rough skin, growth hillocks, and natural indentation marks
Origin
Alluvial or primary kimberlite deposit origin; undetermined specific country
Treatment Detection
No treatments detected; completely untreated natural rough stone
Estimated Value
Varies by weight and specific purity, typically a few hundred to a thousand dollars for industrial/low gem-quality rough
Certification Estimate
GIA or similar major laboratory would issue a rough diamond report or weight/authenticity certificate
Investment Potential
Collector or novelty value rather than high-tier investment grade due to lower clarity
Similar Diamonds
Other alluvial rough diamond specimens of comparable size and clarity
Setting Suggestions
Can be set in an organic, raw-style bezel setting using yellow or white gold to highlight its natural beauty
Care & Maintenance
Standard cleaning with warm soapy water and a soft brush; avoid harsh chemicals and impact
