Uncut octahedral or rough crystal form

Overall Assessment

An interesting and substantial natural rough diamond crystal showcasing raw geological characteristics before human intervention and faceting.

Cut Quality

Not applicable (uncut rough specimen)

Brilliance

Low in rough form; will increase significantly upon cutting and polishing

Fire

Muted in rough state due to unpolished surfaces

Scintillation

Minimal to none in current rough state

Proportions

Natural rough proportions, requires professional mapping and planning

Symmetry

Natural crystal symmetry (cubic/octahedral habit)

Polish

Natural unpolished crystal faces (trigons potentially present)

Fluorescence

Indeterminate from visual assessment alone

Inclusions

Internal clouds, feather fractures, and micro-crystals visible within the matrix

Blemishes

Natural surface etching, rough skin, and growth lines

Origin

Natural rough diamond, likely from primary kimberlitic or alluvial African or Canadian deposits

Treatment Detection

None detected; entirely untreated natural rough crystal

Estimated Value

Variable depending on final cut yield, estimated $1,500 - $4,000 as a rough specimen

Certification Estimate

GIA or IGI would classify this as a rough diamond specimen for grading post-cut

Investment Potential

Moderate as a collector specimen or speculative rough purchase

Similar Diamonds

Comparable to industrial or lower-gem grade run-of-mine natural rough diamonds

Setting Suggestions

Can be mounted raw in organic or rustic bespoke jewelry settings using gold or platinum prongs
