Natural rough diamond crystal
Natural rough diamond crystal · Rough / Uncut irregular crystal formation
Not applicable (Rough, uncut crystal) Cut
Carat
Estimated 2.0 to 3.5 carats based on visual proportions relative to fingers
Color
Near-colorless to light brown tint (approx. G-I range with some body color variation)
Clarity
Included (I1-I2) due to prominent internal fractures and mineral inclusions
Shape
Rough / Uncut irregular crystal formation
Overall Assessment
An interesting, substantial natural rough diamond crystal showing raw geological characteristics, ideal for mineral collectors or custom lapidary work
Cut Quality
Not applicable (Rough, uncut crystal)
Brilliance
Low to moderate due to rough unpolished surfaces and internal fractures
Fire
Limited dispersion visible internally through transparent windows
Scintillation
Poor due to lack of standard facet alignment and high internal inclusion count
Proportions
Not applicable (Raw unpolished crystal block)
Symmetry
Natural irregular crystal symmetry
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Cannot be determined without UV testing (Likely none to faint blue)
Inclusions
Heavy internal feather fractures, dark carbon spots, and mineral staining
Blemishes
Natural surface etch channels, pits, and rough skin adhering matrix
Origin
Alluvial or primary kimberlitic deposit (African or Brazilian origin likely)
Treatment Detection
None detected; appears entirely untreated and natural
Estimated Value
$500 - $1,500 depending on cutter yield and final polished recovery potential
Certification Estimate
GIA or similar major lab if submitted for rough report, expected grade: Natural Diamond Rough
Investment Potential
Moderate value as a unique specimen piece, though high risk for cutting yield
Similar Diamonds
Other alluvial rough diamond crystals of comparable weight and clarity
Setting Suggestions
Best preserved as a raw mineral specimen or custom organic-style bezel setting if polished into a unique baroque stone
Care & Maintenance
Store separately from other jewelry to prevent scratching; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural geological history, often showing growth lines and dissolution features called trigons on their faces
