Rough diamond crystal (Natural)
Rough diamond crystal (Natural) · Uncut octahedral or rough crystal form
Not applicable (uncut rough specimen) Cut

Carat
Estimated > 5.00 carats based on visible rough matrix scale
Color
Near-colorless to white rough (estimated G-I range if cut)
Clarity
Included (rough stone with internal cloudiness and crystal inclusions)
Shape
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
Care & Maintenance
Store separately to prevent scratching other materials; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds often display triangular growth features called trigons on their natural octahedral faces
