Overall Assessment
An interesting, substantial natural rough diamond crystal displaying characteristic rough features. It holds potential for cutting into a faceted stone, though clarity and color limitations will dictate the final polished value.
Cut Quality
Not Applicable (Rough, uncut crystal)
Brilliance
Low to moderate due to rough surface and lack of faceting
Fire
Minimal visible fire in current rough state
Scintillation
Negligible until cut and polished
Proportions
Not Applicable for rough stone
Symmetry
Natural crystal asymmetry with irregular growth faces
Polish
Raw, unpolished natural crystal skin with triangular etch markings (trigons)
Fluorescence
Cannot be determined without UV light testing (typically Medium to Strong Blue in natural roughs)
Inclusions
Heavy internal clouding, feather fractures, and potential crystal inclusions
Blemishes
Natural surface pitting, rough skin, indentations, and growth lines
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin typical for rough specimens)
Treatment Detection
No treatments detected; completely natural rough crystal
Estimated Value
Dependent on final yield after cutting, approximately $1,500 to $4,000 USD as rough specimen
Certification Estimate
GIA or similar major lab if submitted for rough certification and mapping
Investment Potential
Moderate, primarily valued as a collectible mineral specimen or for its potential polished yield
Similar Diamonds
Industrial or lower-gem quality rough diamond crystals of comparable size
Setting Suggestions
Can be set raw in a custom organic wire-wrap or bezel setting, though typically sent to a cutter for brilliant faceting
Care & Maintenance
Store separately from other gemstones to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds often feature natural triangular etch marks called trigons on their octahedral faces, formed by dissolving fluids deep within the Earth
