Natural rough diamond crystal
Natural rough diamond crystal · Uncut octahedral or irregular crystal habit
Not applicable (uncut rough crystal) Cut
Carat
Estimated 0.5 to 1.0 carat based on visual perspective
Color
Near-colorless to faint yellow (approximate G-J range)
Clarity
Included (I1-I3 equivalent for rough crystal with surface naturals and internal feathers)
Shape
Uncut octahedral or irregular crystal habit
Overall Assessment
A fascinating natural rough diamond crystal displaying raw geological character, best appreciated in its organic form or carefully mapped for a custom cut.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Low due to unpolished rough surfaces diffusing light
Fire
Minimal dispersion visible through rough outer skin
Scintillation
Limited flash due to lack of standard facets
Proportions
Natural rough proportions, requires sawing and faceting planning
Symmetry
Natural asymmetrical growth form
Polish
Raw natural crystal faces (octahedral faces with trigons potentially present)
Fluorescence
Indeterminate from visual inspection alone
Inclusions
Visible internal feathers, clouds, and potential mineral crystals
Blemishes
Natural surface pitting, rough skin, and possible trigons
Origin
Natural alluvial or primary kimberlite pipe deposit
Treatment Detection
No evidence of artificial enhancement; untreated rough state
Estimated Value
Modest value as a rough specimen, highly dependent on internal sawing yield
Certification Estimate
GIA or similar primary laboratory for origin and authenticity verification
Investment Potential
Collector value as a rough specimen rather than standard polished investment grade
Similar Diamonds
Unmented rough diamond crystals from African or Canadian primary sources
Setting Suggestions
Raw mineral bezel setting or custom organic wrap to preserve its natural form
Care & Maintenance
Store separately to avoid scratching other gems; clean gently with warm soapy water
Interesting Facts
Rough diamonds retain the ancient geological memory of Earth's mantle before human cutting
