Natural rough diamond crystal
Natural rough diamond crystal · Uncut raw crystal (irregular octahedron/fragment)
Not applicable (rough, uncut stone) Cut
Carat
Estimated 1.5 to 2.5 carats based on visual scale
Color
Estimated G-I near-colorless range
Clarity
Estimated SI1-SI2 (visible internal fractures and crystal inclusions)
Shape
Uncut raw crystal (irregular octahedron/fragment)
Overall Assessment
An interesting, translucent natural diamond rough displaying characteristic crystal growth features, offering great potential for custom cutting or preservation as a raw specimen jewelry piece
Cut Quality
Not applicable (rough, uncut stone)
Brilliance
Moderate to low due to rough surfaces diffusing light
Fire
Limited surface fire, will increase dramatically upon proper cutting and faceting
Scintillation
Minimal in rough form; scintillation depends entirely on future cut geometry
Proportions
Natural rough proportions, requires professional mapping for cutting
Symmetry
Natural octahedral crystal symmetry, slightly distorted
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Cannot be determined without UV testing, likely None to Faint
Inclusions
Internal cleavage planes, feathers, and potential pinpoint inclusions
Blemishes
Natural surface etch channels, growth lines, and rough edges
Origin
Likely alluvial or primary kimberlite deposit origin (African or Canadian source)
Treatment Detection
No treatments detected; completely natural untreated rough crystal
Estimated Value
Varies widely between $500 to $1,500 depending on final yield after cutting and internal stress
Certification Estimate
GIA or IGI would issue a rough diamond report or origin certificate prior to cutting
Investment Potential
Moderate speculative value; high upside if cut and polished successfully into a high-clarity stone
Similar Diamonds
Comparable to standard industrial-to-gem grade run-of-mine natural rough diamonds
Setting Suggestions
Can be set raw in organic, rustic bespoke jewelry using bezel or prong settings in yellow or rose gold
Care & Maintenance
Store separately to prevent scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain the ancient geological memory of Earth's mantle, often featuring natural triangular growth marks called trigons
