Natural Diamond (Rough / Uncut Specimen)
Natural Diamond (Rough / Uncut Specimen) · Raw Octahedron / Irregular Rough Crystal
Not Applicable (Uncut Rough) Cut
Carat
Estimated 1.5 - 2.5 carats
Color
Near Colorless to Faint Yellow (G-J range equivalent)
Clarity
Included (I1-I2 equivalent due to visible internal clouds and feathering)
Shape
Raw Octahedron / Irregular Rough Crystal
Overall Assessment
This is an intriguing natural rough diamond specimen exhibiting characteristic crystal growth features and internal inclusions, offering potential for a unique custom-cut gem or a valued raw collector's piece
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Limited; reflective primarily off natural crystal faces rather than precision-cut facets
Fire
Minimal dispersion observed due to lack of standard pavilion and crown facet angles
Scintillation
Low; produces flashes only when moved under direct light due to rough exterior
Proportions
Natural uncut crystal morphology; high depth ratio due to rough state
Symmetry
Natural Crystal Symmetry (Distorted Octahedral Habit)
Polish
Natural Crystal Faces (Trigons and Striations visible)
Fluorescence
Cannot be determined without UV testing (Likely Faint to Medium Blue)
Inclusions
Internal cloud formations, pinpoint inclusions, and potential feather fractures visible beneath the surface
Blemishes
Natural surface pitting, trigons (growth marks), and minor surface irregularities typical of rough diamond stones
Origin
Alluvial or primary kimberlite deposit (African or Canadian origin likely)
Treatment Detection
None detected; appears entirely natural and untreated in its rough state
Estimated Value
$500 - $1,500 depending on weight, final cut yield, and clarity retention after processing
Certification Estimate
GIA or IGI (Rough Diamond Evaluation / Report)
Investment Potential
Moderate; primarily valued as a collector's specimen or bespoke jewelry piece rather than standard investment stones
Similar Diamonds
Other unpolished industrial or collector-grade rough diamond octahedrons
Setting Suggestions
Organic bezel setting or custom raw stone prong mount to preserve its natural crystalline character
Care & Maintenance
Avoid harsh impacts which could exploit natural cleavage planes; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds often feature tiny triangular indentation marks called trigons, which form naturally as a result of crystal dissolution during ascent to the Earth's surface
