Carat
Estimated 2.0 - 3.5 carats
Color
Estimated Near Colorless to Faint Yellow (G-J range)

Overall Assessment
This is an authentic natural rough diamond crystal fragment, showing characteristic growth features and inclusions, holding potential for custom cutting or raw jewelry design.
Cut Quality
Not Applicable (Rough unpolished stone)
Brilliance
Low to moderate due to unpolished and rough crystal state
Fire
Minimal visible fire prior to faceting and polishing
Scintillation
Low, limited by rough surface scattering light rather than internal reflection
Proportions
Natural rough geometry, non-standard proportions prior to cutting
Symmetry
Natural crystal symmetry (distorted octahedral/fragmented)
Polish
Natural crystal faces (trigons and rough texture)
Fluorescence
Cannot be determined visually without UV light testing (typically Medium to Strong Blue in natural roughs)
Inclusions
Surface and internal dark mineral inclusions, feathers, and cloud patches typical of rough diamonds
Blemishes
Natural surface pitting, rough skin, and possible abrasions from extraction
Origin
Likely alluvial or primary kimberlite pipe deposit (African, Canadian, or Russian origin)
Treatment Detection
No signs of artificial treatment; completely natural rough diamond
Estimated Value
Varies widely depending on cutting yield, estimated $1,000 to $3,500 USD for rough stone
Certification Estimate
GIA or local gemological laboratory for rough diamond parcel evaluation
Investment Potential
Moderate to high as a raw collectible or speculative asset depending on potential cut yield

Setting Suggestions
Can be set raw/uncut in organic or rustic bespoke jewelry using bezel or prong settings in yellow or rose gold
Care & Maintenance
Store separately to avoid scratching other gems; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their geological history, showing natural growth marks like trigons on their crystal faces
