Natural rough diamond crystal
Natural rough diamond crystal · Uncut octahedral/irregular rough crystal
Not applicable to rough crystals (Uncut/Unpolished) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual proportions
Color
Near-colorless to light brown tint (K-M range approximately)
Clarity
Included (I1-I2 range) with visible internal feathers and mineral inclusions
Shape
Uncut octahedral/irregular rough crystal
Overall Assessment
A fascinating, untreated natural diamond crystal showcasing raw geological formation features, growth lines, and natural surface textures.
Cut Quality
Not applicable to rough crystals (Uncut/Unpolished)
Brilliance
Low brilliance due to uncut, rough surface and natural opacity
Fire
Minimal dispersion visible through raw crystal faces
Scintillation
Limited flash due to lack of standard facet patterns
Proportions
Natural rough proportions, deep untrimmed crystal habit
Symmetry
Natural crystal symmetry showing octahedral growth lines and trigons
Polish
Natural crystal faces (no polish applied)
Fluorescence
Cannot be determined without UV testing (Likely Medium Blue typical of many rough diamonds)
Inclusions
Internal clouds, feathers, and brownish mineral spots visible
Blemishes
Natural surface etch channels, growth lines, and trigons
Origin
Natural alluvial or primary kimberlitic deposit origin
Treatment Detection
No treatments detected; completely untreated natural rough
Estimated Value
Varies by industrial vs gemstone utility, roughly $1,500 to $3,500 USD for specimen/cutting rough
Certification Estimate
GIA or similar major lab for rough origin verification
Investment Potential
Moderate value as a unique mineral specimen or educational piece rather than standard investment diamond
Similar Diamonds
Comparable natural uncut industrial and lower-gem grade diamond crystals
Setting Suggestions
Best kept as a raw mineral specimen or custom-designed organic raw diamond mounting in yellow or white gold
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to internal natural stress fractures
Interesting Facts
Displays distinct natural crystal growth lines (layers) and trigons (triangular depressions) on the face, characteristic of unpolished diamond rough
