Rough octahedral / irregular crystal form

Overall Assessment

An interesting, substantial natural rough diamond crystal showing raw geological characteristics, ideal for custom cutting or as a collector's mineral specimen

Cut Quality

Not applicable (Rough, un-cut crystal specimen)

Brilliance

Low to moderate due to rough unpolished state and surface texture

Fire

Limited dispersion visible on raw surfaces

Scintillation

Minimal flash effect typical of rough diamond crystal skins

Proportions

Natural rough stone with natural facets, depth and table percentages do not apply

Symmetry

Natural crystal symmetry, distorted octahedral form

Polish

Natural crystal faces (some trigons or striations potentially present)

Fluorescence

Cannot be determined without UV testing, likely None to Faint

Inclusions

Internal feathers, clouds, and mineral crystal inclusions visible

Blemishes

Natural surface etch channels, pits, and rough skin

Origin

Likely alluvial or primary pipe deposit origin (African or Canadian rough source)

Treatment Detection

No signs of artificial treatment; appears completely untreated rough

Estimated Value

Varies widely as a rough specimen, roughly $1,000 to $3,000 depending on cutter yield and final polished weight

Certification Estimate

GIA or similar major gemological laboratory report for rough stones

Investment Potential

Moderate, primarily valued as a collector's mineral specimen or custom lapidary potential

Similar Diamonds

Comparable unpolished alluvial rough diamond specimens of similar size

Setting Suggestions

Can be mounted in a bespoke organic raw-stone bezel setting using yellow or white gold
