Natural diamond (uncut / rough crystal specimen)
Natural diamond (uncut / rough crystal specimen) · Rough crystal / elongated octahedral or irregular fragment
Not applicable (uncut rough crystal) Cut
Carat
Estimated 1.5 to 2.5 carats
Color
Near-colorless to light brown tint (approx. G-I range)
Clarity
Included (I1-I3 range due to prominent internal fractures and inclusions)
Shape
Rough crystal / elongated octahedral or irregular fragment
Overall Assessment
An interesting natural rough diamond crystal featuring prominent internal fractures and a distinct elongated habit, best suited for collection as a mineral specimen rather than traditional jewelry cutting.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Low to moderate due to heavy internal fracturing and lack of standard facets
Fire
Minimal dispersion due to rough surface and internal inclusions
Scintillation
Limited, reflecting light irregularly off natural crystal faces and internal planes
Proportions
Natural elongated crystal morphology without standard faceted proportions
Symmetry
Natural asymmetric crystal growth form
Polish
Raw, natural crystal faces (some minor abrasion likely present)
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Heavy internal feather fractures, carbon spots, and crystal inclusions visible
Blemishes
Natural surface etch channels, trigons, and rough skin textures
Origin
Alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of treatment; completely natural rough specimen
Estimated Value
Low commercial value as a gem, primarily of mineralogical or collector interest
Certification Estimate
GIA or similar major lab, typically graded as rough industrial or low-clarity ornamental gem material
Investment Potential
Minimal as a financial investment; valued mainly as a geological specimen
Similar Diamonds
Other low-clarity rough diamond octahedrons and industrial-grade diamond crystals
Setting Suggestions
Raw mineral specimen display mount, organic bezel setting, or wire-wrapped pendant
Care & Maintenance
Handle with care to prevent chipping along natural cleavage planes; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural geological form, showing the octahedron or dodecahedron growth patterns formed deep within the Earth's mantle.
