Natural rough diamond
Natural rough diamond · Rough uncut crystal (octahedral/irregular morphology)
Not applicable (uncut rough crystal) Cut
Carat
Estimated between 1.5 to 2.5 carats based on visual scale against fingers
Color
Estimated near-colorless to faint tint (G-J range)
Clarity
Estimated SI1 to SI2 (inclusions visible internally, typical for unpolished rough)
Shape
Rough uncut crystal (octahedral/irregular morphology)
Overall Assessment
A charming and authentic natural rough diamond crystal displaying characteristic morphology, offering great potential for custom lapidary work or as an organic raw jewelry centerpiece
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Limited in rough form; will display high brilliance once properly faceted and polished
Fire
Obscured by rough surface texture; high dispersion potential post-cutting
Scintillation
Minimal play of light in current rough state; excellent scintillation expected after cutting
Proportions
Natural rough proportions, requires professional mapping for optimal cutting yield
Symmetry
Natural crystallographic symmetry (octahedral growth tendencies)
Polish
Raw natural crystal faces (trigons and striations likely present)
Fluorescence
Cannot be determined without UV testing (estimated None to Faint)
Inclusions
Internal crystal inclusions, feathers, or cloud clusters typical of natural rough
Blemishes
Natural surface etchings, trigons, and surface graining
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
No treatments detected; untreated natural rough crystal
Estimated Value
Varies widely based on final cut yield, estimated $2,000 to $5,000 USD as rough specimen
Certification Estimate
GIA or IGI rough evaluation service prior to cutting
Investment Potential
Moderate to high as a raw collectible mineral specimen or custom-cut investment diamond
Similar Diamonds
Comparable to unpolished run-of-mine natural diamond rough parcels of similar size and clarity
Setting Suggestions
Can be set raw in an organic/rustic bespoke mounting, or cut into a modern brilliant shape for a classic prong setting
Care & Maintenance
Store separately in a soft pouch; clean with mild soapy water and a soft brush
Interesting Facts
Rough diamonds retain the ancient geological memory of the earth's mantle, often containing microscopic fluid or mineral inclusions billions of years old
