Uncut rough stone Cut
Carat
Estimated 0.50 to 1.00 carat based on visual context
Color
Near colorless to faint yellow (approx. G-J range)

Included (approx. I1-I2)
Shape
Rough octahedron or irregular crystalline form
Overall Assessment
An interesting specimen of a natural, uncut rough diamond crystal showing distinct growth features, awaiting professional evaluation for cutting potential.
Cut Quality
Uncut rough stone
Brilliance
Low due to rough, unpolished state
Fire
Limited dispersion due to lack of faceted cuts
Scintillation
Minimal sparkle prior to cutting and polishing
Proportions
Natural uncut proportions with curved growth lines (trigons or lamellae visible)
Symmetry
Natural asymmetrical rough crystal growth
Polish
Raw unpolished crystal faces (natural octahedral habit)
Fluorescence
Unable to determine without UV testing (likely none to faint)
Inclusions
Internal cloudiness, feathers, and natural growth lines visible
Blemishes
Natural surface features, etch channels, and rough skin
Origin
Natural alluvial or primary kimberlite pipe deposit
Treatment Detection
No treatments detected (untreated rough crystal)
Estimated Value
Varies widely based on industrial vs gem-grade yield potential, roughly $100 - $500
Certification Estimate
GIA rough diamond evaluation report
Investment Potential
Speculative, as rough stone value depends entirely on the cut yield after processing

Setting Suggestions
Can be custom-set in an organic raw diamond ring using yellow gold or platinum prongs
Care & Maintenance
Store separately from other jewelry to avoid scratching softer materials, clean gently with warm soapy water
Interesting Facts
The growth lines and trigons on the surface are natural growth marks formed deep within the Earth's mantle over billions of years
