Natural rough diamond crystal
Natural rough diamond crystal · Uncut raw crystal, irregularly shaped octahedral/dodecahedral fragment
Not applicable (Rough, unpolished crystal) Cut

Carat
Estimated 1.50 to 2.50 carats based on visual proportions and scale
Color
Near-colorless to faint brownish tint (approximate G-I range)
Clarity
Included (I1 to I2 range due to internal cloudiness and fractures)
Shape
Uncut raw crystal, irregularly shaped octahedral/dodecahedral fragment
Overall Assessment
An interesting and characterful natural rough diamond crystal showing typical geological features, offering high potential for a bespoke custom cut or a unique rustic jewelry design.
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low to moderate due to rough surface and internal clouding; will increase significantly upon cutting
Fire
Minimal in rough state; dispersion will emerge once properly faceted
Scintillation
Limited flash effect from natural crystal windows and facets
Proportions
Irregular rough dimensions; depth and table percentages do not apply
Symmetry
Natural asymmetric crystal growth formations
Polish
Natural crystal faces showing trigons, striations, and rough surface texture
Fluorescence
Indeterminate from visual assessment alone; requires UV light testing
Inclusions
Internal clouds, feather fractures, and potential pinpoint inclusions visible
Blemishes
Natural surface textures, pitting, and rough skin characteristic of alluvial or primary deposits
Origin
Likely alluvial or primary kimberlite source; visual indicators are non-conclusive without advanced spectroscopy
Treatment Detection
No obvious signs of artificial treatments; appears entirely natural and untreated
Estimated Value
Varies widely based on potential yield after cutting; raw speculative value estimated moderately
Certification Estimate
GIA or similar major lab would issue a rough diamond report or diamond dossier after cutting
Investment Potential
Moderate speculative value; high potential upside if cut and polished skillfully, though risk of weight loss exists
Similar Diamonds
Other natural alluvial rough diamond crystals of comparable size and clarity
Setting Suggestions
Can be set raw in organic, rustic, or bezel settings for an earthy, bespoke jewelry piece
Care & Maintenance
Standard care for rough gemstones; avoid harsh chemicals and ultrasonic cleaning if fractures reach the surface
Interesting Facts
Rough diamonds retain their geological history, often showcasing natural growth marks like trigons formed deep within the Earth's mantle
