N/A (Rough/Raw State) Cut
Carat
Estimated 5.0 - 8.0 carats based on crystalline structure volume
Color
Near Colorless (Estimated G-I range)
Clarity
SI1 - SI2 (Visible internal graining and surface reaching inclusions)
Shape

Overall Assessment
A high-quality natural rough diamond with significant potential for a large polished yield, possibly an emerald or cushion cut.
Cut Quality
N/A (Rough/Raw State)
Brilliance
Low (Due to rough surface scattering light)
Fire
Low (Prismatic effects visible in internal fractures)
Scintillation
Low
Proportions
N/A (Unfaceted)
Symmetry
Poor (Natural crystal symmetry)
Polish
N/A (Natural matte and trigonal textures)
Fluorescence
Indeterminable from image
Inclusions
Internal graining, feathers, and possible mineral inclusions
Blemishes
Natural trigons, growth lines, and percussion marks on the surface
Origin
Alluvial source (Likely Africa or Russia)
Treatment Detection
None detected; appears to be in its natural state
Estimated Value
$5,000 - $12,000 USD (Depending on yield and clarity after cutting)
Certification Estimate
GIA Rough Diamond Evaluation
Investment Potential
Moderate (Value is tied to the potential grade of the finished stone)
Similar Diamonds
Uncut octahedral or dodecahedral natural crystals
Setting Suggestions
Bezel or claw setting for 'raw' jewelry, or laser-mapped for faceted cutting
Care & Maintenance
Avoid high-pressure ultrasonic cleaners if deep feathers are present
Interesting Facts
The parallel striations on the surface are characteristic of the diamond's cubic crystal system growth.
