Not applicable (rough crystal) Cut
Carat
Estimated 3.5 - 5.0 carats
Color
Near colorless to faint yellow (approx. G-J)
Clarity
Included (approx. I1 - I2 due to internal fractures and surface features)
Shape
Rough crystal / Uncut octahedron fragment
Overall Assessment
An interesting, natural rough diamond crystal showing typical growth patterns and internal characteristics, best appreciated as a raw specimen or carefully cut into a finished gem.
Cut Quality
Not applicable (rough crystal)
Brilliance
Low due to rough, unpolished state and internal fracturing
Fire
Minimal in current rough state
Scintillation
Poor due to lack of standard facet angles
Proportions
Natural rough proportions, deep and irregular
Symmetry
Natural crystal symmetry, distorted
Polish
Natural crystal faces (trigons / growth lines)
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Internal fracture planes, feather inclusions, and mineral inclusions visible
Blemishes
Natural surface etching, trigons, and rough skin
Origin
Likely alluvial or primary kimberlite pipe deposit origin
Treatment Detection
No treatments detected; natural untreated rough stone
Estimated Value
Varies widely based on cutting potential, roughly $500 - $2,000 as a rough specimen
Certification Estimate
GIA would likely issue a Diamond Rough Report or grading report if cut
Investment Potential
Mainly valued as a mineral specimen or collector's rough piece rather than standard investment diamond
Similar Diamonds
Comparable uncut industrial or lower-gem-quality natural diamond crystals
Setting Suggestions
Can be set raw/uncut in organic custom bezels or wire-wrapped designs using yellow or white gold
Care & Maintenance
Store separately to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
