Overall Assessment
This is a fascinating specimen of a natural, uncut diamond crystal. While unsuitable for standard jewelry without cutting and polishing, its raw beauty and geological character make it a wonderful piece for mineral collectors.
Cut Quality
Not applicable (Rough, unpolished stone)
Brilliance
Low to moderate due to rough, unpolished surfaces scattering light internally
Fire
Limited surface dispersion visible through raw windows
Scintillation
Minimal to none due to lack of standard faceted pavilion and crown
Proportions
Natural octahedral or irregular growth habit proportions
Symmetry
Natural irregular crystal symmetry
Polish
Raw, unpolished natural crystal faces and resorption features
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Visible internal feathers, cleavage planes, and cloud-like inclusions
Blemishes
Natural surface trigons, etch channels, and rough skin
Origin
Likely alluvial or primary kimberlite pipe deposit
Treatment Detection
No visible signs of artificial treatments; entirely natural state
Estimated Value
