Natural Rough Diamond
Natural Rough Diamond · Uncut Octahedral / Irregular Crystal
Not Applicable (Uncut Rough) Cut
Carat
Estimated 1.50 - 2.50 carats (rough crystal)
Color
Near Colorless to Faint Yellow (approx. G-J equivalent)
Clarity
Included (I1-I2 equivalent due to prominent internal feathers and surface features)
Shape
Uncut Octahedral / Irregular Crystal
Overall Assessment
This is an interesting, natural rough diamond crystal displaying typical surface features and internal inclusions of an unworked stone, offering potential for custom lapidary work or preservation as a mineral specimen.
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low due to rough, unpolished state and scattering of light
Fire
Minimal visible fire in current rough state
Scintillation
Limited flash due to irregular, unpolished faces
Proportions
Natural uncut crystal proportions, deep and elongated
Symmetry
Natural Asymmetric Crystal Formation
Polish
Natural Unpolished Surface with Etching Features
Fluorescence
Likely Faint to Medium Blue (common in rough natural stones under UV)
Inclusions
Feathers, pinpoints, and natural cloud-like inclusions visible internally
Blemishes
Natural growth lines, trigons, and surface pitting typical of rough crystals
Origin
Likely alluvial or primary kimberlitic deposit (African or Canadian origin)
Treatment Detection
Untreated, completely natural as-mined condition
Estimated Value
Varies significantly by exact weight and purity, typically valued lower as rough material before cutting and polishing
Certification Estimate
GIA or similar lab would issue a Rough Diamond Identification Report
Investment Potential
Holds intrinsic value as a natural mineral specimen; value depends heavily on potential yield if cut
Similar Diamonds
Other alluvial or mine-run rough industrial/gem-grade diamond crystals
Setting Suggestions
Organic raw crystal jewelry settings using bezel or wire-wrap in yellow or white gold
Care & Maintenance
Store separately to prevent scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural geological history, showing crystal growth markings like trigons formed millions of years ago deep within the Earth's mantle
