Not applicable (uncut rough specimen) Cut
Carat
Estimated 2.0 - 4.0 carats based on rough visual volume
Color
Near colorless to slightly tinted (approx. G-J range)
Clarity
Included (I1-I3) due to surface features and internal irregularities
Shape
Rough uncut octahedral or irregular crystalline form
Overall Assessment
An interesting and authentic-appearing natural rough diamond specimen showcasing classic crystal growth features and untouched natural surfaces
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low to moderate due to rough, unpolished exterior surfaces diffusing light
Fire
Minimal due to lack of faceted optical design
Scintillation
Poor, as light does not return through structured facets
Proportions
Uncut crystal habit, non-standard geometric proportions
Symmetry
Natural crystal symmetry showing typical growth lines and striations
Polish
Raw, unpolished natural crystal faces with striations (trigons or etch channels)
Fluorescence
Indeterminate from visual inspection alone
Inclusions
Natural mineral inclusions, feathers, and internal cloudiness typical of rough stones
Blemishes
Natural surface textures, pitting, trigons, and rough skin characteristic of unworked diamond crystal

Estimated Value
Varies widely depending on exact weight, internal purity, and industrial vs. gem grade classification
