Natural Diamond (or rough/uncut diamond crystal specimen)
Natural Diamond (or rough/uncut diamond crystal specimen) · Rough Crystal / Uncut Octahedral / Irregular
Not Applicable (Uncut rough specimen) Cut
Carat
Estimated 2.50 to 4.00 carats (based on typical close-up macro visual perspective of a crystal fragment)
Color
Near Colorless to Faint Yellow (G-J range)
Clarity
Included (I1-I2 due to prominent internal fractures, feathers, and crystal inclusions visible in macro view)
Shape
Rough Crystal / Uncut Octahedral / Irregular
Overall Assessment
An intriguing natural diamond crystal showcasing raw geological characteristics, internal stress fractures, and authentic growth features ideal for specimen collectors or bespoke organic jewelry creation
Cut Quality
Not Applicable (Uncut rough specimen)
Brilliance
Subdued due to rough exterior and internal fractures diffusing light
Fire
Limited dispersion visible primarily through clear window areas
Scintillation
Minimal sparkle, characterized more by internal reflections from cleavage planes
Proportions
Natural crystal form, proportions defined by crystal habit rather than facet angles
Symmetry
Natural crystalline symmetry showing octahedral growth features and trigons
Polish
Natural rough crystal surface with typical growth steps and minor etching
Fluorescence
Inert to Faint Blue (common in natural rough crystals under UV light)
Inclusions
Prominent internal feathers, cleavage planes, fracture lines, and dark crystal inclusions visible
Blemishes
Natural surface naturals, striations, and minor surface pitting from host rock
Origin
Likely alluvial or primary kimberlitic origin (African or Canadian sources typical)
Treatment Detection
No signs of artificial treatment; completely natural rough state
Estimated Value
Varies widely based on cutter's yield potential, roughly $1,000 to $3,500 for industrial/commercial grade rough
Certification Estimate
GIA or IGI (Rough Diamond Report / Origin Report if submitted)
Investment Potential
Moderate, primarily valued as a collectible mineral specimen or custom artisan cut candidate
Similar Diamonds
Other industrial or jewelry-grade uncut diamond crystals and natural octahedrons
Setting Suggestions
Organic bezel setting or raw crystal pendant mounting to preserve its natural untamed aesthetic
Care & Maintenance
Store separately to prevent scratching other stones; avoid harsh chemical ultrasonic cleaners due to internal fractures
Interesting Facts
Uncut diamonds often show natural triangular etch markings called trigons on their faces formed by hot solvent fluids deep within the Earth
