Natural rough diamond crystal
Natural rough diamond crystal · Uncut raw crystal (irregular elongated octahedral fragment)
Not applicable (Rough, unpolished stone) Cut
Carat
Estimated 2.5 - 3.5 carats
Color
Near-colorless to light brown tint (approx. G-I range)
Clarity
Included (I1-I2 equivalent due to internal fracture lines and cloudiness)
Shape
Uncut raw crystal (irregular elongated octahedral fragment)
Overall Assessment
An interesting and genuine natural rough diamond specimen exhibiting raw geological character, featuring visible growth features and internal fractures typical of unpolished stones
Cut Quality
Not applicable (Rough, unpolished stone)
Brilliance
Low to moderate due to raw, unpolished surfaces and internal fractures
Fire
Limited dispersion visible only through translucent natural windows
Scintillation
Minimal sparkle; reflects light diffusely off natural crystal faces
Proportions
Natural rough proportions, deep and elongated
Symmetry
Natural crystal asymmetry with distorted growth features
Polish
Raw, natural crystal faces (trigons and striations visible)
Fluorescence
Indeterminate from visual inspection
Inclusions
Internal fracture planes, feather inclusions, and dark mineral spots
Blemishes
Natural surface etch channels, pits, and rough edges
Origin
Likely alluvial or primary kimberlite deposit (African or Canadian origin)
Treatment Detection
No treatments detected; appears entirely untreated and natural
Estimated Value
Variable based on cutting potential, roughly $500 - $1,500 USD
Certification Estimate
GIA or similar major lab would issue a rough diamond report or report as natural rough
Investment Potential
Moderate as a collector specimen, depends heavily on yield if cut and polished
Similar Diamonds
Other natural industrial or jewelry-grade rough diamond crystals of comparable size
Setting Suggestions
Best suited for organic raw crystal jewelry, such as a custom bezel setting in yellow or white gold
Care & Maintenance
Store carefully to prevent chipping along natural cleavage planes; clean gently with warm soapy water
