Rough Natural Diamond (Uncut Crystal Fragment)
Rough Natural Diamond (Uncut Crystal Fragment) · Raw, Uncut Crystal (Irregular Fragment)
Not Applicable (Uncut Rough) Cut
Carat
Estimated 1.5 - 2.5 carats
Color
Near-colorless to light brown tint (J-K range)
Clarity
Included (I1 - I2 due to internal fractures and natural growth irregularities)
Shape
Raw, Uncut Crystal (Irregular Fragment)
Overall Assessment
This is an authentic, untreated rough diamond crystal fragment. While it possesses lower clarity and visible fractures in its current raw state, skilled cutting and polishing could salvage a small, included polished stone, though it is often more appealing to collectors in its raw, organic form.
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low to moderate due to rough surfaces and fracture planes
Fire
Minimal in current rough state, depends on future cutting
Scintillation
Poor in raw form; light refraction is scattered
Proportions
Uncut natural morphology
Symmetry
Natural Asymmetry (Raw crystal formation)
Polish
Raw natural crystal surfaces and conchoidal fracture planes
Fluorescence
Unknown (requires UV testing)
Inclusions
Internal feather fractures, carbon spots, and natural crystal growth lines
Blemishes
Natural surface textures, trigons (potentially), and fracture steps
Origin
Natural alluvial or primary kimberlite deposit (African or Canadian origin likely)
Treatment Detection
No signs of treatment; completely untreated natural rough
Estimated Value
$300 - $800 depending on cutting potential and final polished yield
Certification Estimate
GIA or similar major lab if submitted as a rough diamond for origin tracking
Investment Potential
Low as a raw specimen for mainstream investment, but moderate speculative value for custom cutters
Similar Diamonds
Comparable to industrial or lower-gem-quality rough diamond parcels sold to custom cutters
Setting Suggestions
Raw mineral pendant setting using yellow or rose gold to complement the natural earth-toned inclusions
Care & Maintenance
Store separately to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds show the natural octahedral or irregular crystal shapes formed deep within the Earth's mantle over billions of years
