Carat
Estimated 1.50 - 2.50 carats based on visual scale
Color
Estimated near-colorless to light yellow (G-K range)
Clarity
Estimated Included (I1-I3) due to visible interior cloudiness and inclusions
Shape
Rough octahedral / uncut crystal form
Overall Assessment
A fascinating, natural rough diamond crystal displaying classic geological formation characteristics prior to any lapidary cutting or polishing.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Low (rough surface unpolished, diffusing light)
Fire
Low in current rough state
Scintillation
Minimal due to unpolished crystal faces
Proportions
Natural crystal habit with growth layers
Symmetry
Natural crystal symmetry (octahedral faces)
Polish
Natural crystal face texture (trigons potentially present)
Fluorescence
Cannot be determined without UV testing (Likely None to Faint)
Inclusions
Internal clouds, crystals, and potential feathers visible in the matrix
Blemishes
Natural surface pitting, trigons, and rough growth steps
Origin
Natural geological origin (African, Canadian, or Russian primary source regions)
Treatment Detection
No treatments detected; completely natural rough stone
Estimated Value
Varies widely by exact weight and purity, roughly $1,000 - $3,000 for raw industrial/gem material
Certification Estimate
GIA rough diamond evaluation or Kimberley Process certification
Investment Potential
Collectible value for raw crystal enthusiasts; lower liquidity than cut stones
