Not applicable (Rough, unpolished crystal) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual proportions
Color
Brownish-tinted / Near colorless with natural surface staining
Clarity
Included (I1-I3 estimated due to visible internal fractures and structural flaws)
Shape
Rough crystal / Irregular elongated fragment
Overall Assessment
An intriguing, untreated natural rough diamond crystal displaying characteristic surface textures and internal fracturing, ideal for mineral collectors or custom organic jewelry design
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low to moderate due to rough surfaces and internal fractures obstructing light path
Fire
Limited dispersion visible primarily through internal fractures and windows
Scintillation
Minimal and erratic due to unfaceted, uneven surface geometry
Proportions
Uncut natural crystal form, depth and table percentages do not apply
Symmetry
Natural crystal asymmetry with distorted growth lines
Polish
Raw, unpolished natural crystal faces showing typical trigons and striations
Fluorescence
Cannot be reliably determined without UV light testing
Inclusions
Feathers, clouds, and internal cleavage planes visible
Blemishes
Natural surface etchings, cavities, and trigons
Origin
Alluvial or primary kimberlite pipe deposit (Africa, Canada, or Russia)
Treatment Detection
No signs of artificial treatment; appears completely untreated and natural
Estimated Value
Valued primarily as a mineral specimen rather than a cut gemstone; rough value varies widely by weight and clarity
Certification Estimate
GIA or EGL would issue a rough stone report noting natural origin
Investment Potential
Collected more for rarity and specimen value than traditional diamond investment
Similar Diamonds
Typical run-of-mine industrial or lower-gem-quality rough diamond crystals
Setting Suggestions
Best preserved as a raw mineral specimen or set in a custom organic wire-wrap or bezel setting
Care & Maintenance
Store separately to avoid scratching other items; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds straight from the earth often show natural triangular growth markings called trigons on their faces
