Natural rough diamond crystal
Natural rough diamond crystal · Uncut / Rough crystal form
Not applicable (uncut rough specimen) Cut
Carat
Estimated 3.5 to 5.0 carats based on rough dimensions
Color
Near-colorless to faint yellow tint (G-J range estimated)
Clarity
Included (I1-I2 equivalent due to prominent central inclusions and fractures)
Shape
Uncut / Rough crystal form
Overall Assessment
An intriguing natural rough diamond crystal featuring prominent internal mineral inclusions and structural features, offering potential for either mineral collection display or expert custom cutting to maximize yield.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Limited in rough form, exhibits vitreous to adamantine luster on crystal faces
Fire
Minimal dispersion visible through rough exterior; will increase significantly upon cutting and polishing
Scintillation
Not applicable in current rough state
Proportions
Natural octahedral/elongated rough crystal habit, requires custom cutting analysis
Symmetry
Natural asymmetrical rough growth form
Polish
Natural unpolished crystal faces (trigons and striations visible)
Fluorescence
Cannot be determined without UV testing (likely Faint to Medium Blue)
Inclusions
Large dark internal mineral inclusions, feather fractures, and internal stress planes visible
Blemishes
Natural surface rough etching, pitting, and irregular growth marks
Origin
Likely alluvial or primary kimberlitic deposit origin (African or Canadian source)
Treatment Detection
No treatments detected; completely natural untreated rough crystal
Estimated Value
Rough diamond value varies significantly based on final yield potential, roughly $1,000 to $3,000 USD for the specimen
Certification Estimate
GIA or AGS if polished; rough would require Kimberley Process certificate of origin
Investment Potential
Moderate as a collector specimen; high potential value added if skillfully cut and polished into a finished gemstone
Similar Diamonds
Comparable to standard industrial-to-near-gem quality run-of-mine diamond crystals
Setting Suggestions
Can be preserved as an uncut raw specimen in a bespoke organic bezel setting, or faceted into an elongated shape like an Emerald or Oval cut
Care & Maintenance
Store separately to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
The surface shows natural growth features such as striations and curved faces typical of natural diamond crystallization deep within the Earth's mantle
