Natural rough diamond crystal
Natural rough diamond crystal · Rough elongated crystal / Raw octahedral or flattened habit
Not applicable as this is an uncut rough crystal Cut
Carat
Estimated 0.85 - 1.25 carats based on visual scale
Color
Near colorless to faint brown tint (approx. J-K range)
Clarity
Included (I1-I2 due to internal feathers, clouds, and dark mineral inclusions)
Shape
Rough elongated crystal / Raw octahedral or flattened habit
Overall Assessment
An interesting, genuine natural rough diamond specimen featuring natural surface texture and internal characteristics, ideal for a collector or custom raw-stone jewelry designer.
Cut Quality
Not applicable as this is an uncut rough crystal
Brilliance
Limited due to rough unpolished surfaces and natural inclusions
Fire
Minimal dispersion visible through the rough outer skin
Scintillation
Low; rough surfaces diffuse light rather than returning sharp flashes
Proportions
Natural rough form; no standardized table or pavilion angles exist yet
Symmetry
Natural asymmetric crystal growth formations typical of rough diamond
Polish
Natural unpolished crystal face with typical trigons and striations
Fluorescence
Cannot be definitively determined without UV testing, likely inert to faint
Inclusions
Dark carbon spots, internal feather fractures, and cloud clusters visible
Blemishes
Natural surface etchings, pitting, growth lines, and rough skin
Origin
Likely alluvial deposit origin given the surface wear and rounded edges
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Varies widely based on potential cut yield; rough market value estimated lower than polished equivalent
Certification Estimate
GIA or similar major gemological lab would issue a rough diamond report
Investment Potential
Holds intrinsic mineral value, highly dependent on the cutter's skill if faceted
Similar Diamonds
Other alluvial rough diamond crystals of similar size and clarity
Setting Suggestions
Can be set raw in a custom organic bezel or wire-wrap mounting
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh impacts on cleavage planes
