Natural diamond (uncut, rough crystal specimen) · Rough crystal / Irregular elongated fragment
Not applicable (Rough, unpolished stone) Cut
Carat
Estimated 2.0 to 3.5 carats based on visual scale
Color
Estimated K-M (tinted light yellow to brownish)
Clarity
I2 to I3 (Significant inclusions and structural fractures visible)
Shape
Rough crystal / Irregular elongated fragment
Overall Assessment
This is a raw, uncut natural diamond crystal featuring visible surface striations and internal fracture lines filled with mineral staining. While unsuitable for standard high-end jewelry without extensive cutting and significant weight loss, it serves as an intriguing natural specimen for collectors and bespoke organic jewelry designs.
Cut Quality
Not applicable (Rough, unpolished stone)
Brilliance
Poor to minimal due to rough surfaces and internal fracturing
Fire
Very low, obscured by rough exterior and inclusions
Scintillation
Minimal, lack of faceted reflective surfaces prevents standard sparkle
Proportions
Uncut natural crystal form, no standard table, depth, or pavilion angles
Symmetry
Natural asymmetrical crystal growth
Polish
None (Raw crystal surfaces with natural etch marks and striations)
Fluorescence
Unable to determine without UV testing (likely Faint to Medium Blue if natural)
Inclusions
Heavy internal feathers, cloudiness, crystal inclusions, and mineral staining along fracture planes
Blemishes
Natural surface irregularities, cavities, and trigons typical of rough diamond faces
Origin
Alluvial deposit or primary kimberlite pipe (likely African or Canadian origin based on typical rough appearance)
Treatment Detection
No evidence of artificial treatments; completely natural untreated rough
Estimated Value
Low commercial value as a gemstone due to heavy inclusions and lack of cut, valued primarily as a mineral specimen
Certification Estimate
GIA or similar major lab would grade as rough gem-quality / industrial-grade material
Investment Potential
Low investment potential for resale as a gemstone; primarily of interest to collectors of mineral specimens
Similar Diamonds
Other industrial or low-clarity rough diamond crystals sold for mineral collections or niche uncut jewelry
Setting Suggestions
Raw uncut diamond pendant using a secure wire-wrap or bezel setting to preserve its organic shape
Care & Maintenance
Store separately to avoid scratching other items; clean gently with warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners due to internal fractures
Interesting Facts
Rough diamonds showcase the natural octahedral or distorted crystal growth habits formed deep within the Earth's mantle before human cutting and polishing
