Rough natural diamond specimen (or potentially blue beryl/aquamarine depending on strict mineral testing, but analyzed here as a raw crystal structure)
Rough natural diamond specimen (or potentially blue beryl/aquamarine depending on strict mineral testing, but analyzed here as a raw crystal structure) · Raw crystal / Untouched rough octahedron-like fragment
Not applicable (Rough uncut crystal) Cut
Carat
Estimated 2.50 to 3.50 carats based on visual proportions
Color
Fancy Light Blue to greenish-blue hue
Clarity
Included (I1-I2)
Shape
Raw crystal / Untouched rough octahedron-like fragment
Overall Assessment
An intriguing raw crystalline specimen displaying a distinct bluish tint and natural surface features, requiring professional laboratory testing to confirm absolute diamond identity versus colored gemstone alternatives.
Cut Quality
Not applicable (Rough uncut crystal)
Brilliance
Low due to lack of faceting and surface contamination
Fire
Minimal dispersion observed in current rough state
Scintillation
Limited flash effect due to unpolished raw facets
Proportions
Natural irregular crystal proportions, deep pavilion-like natural growth
Symmetry
Natural asymmetrical raw crystal form
Polish
None (Natural crystalline surface texture)
Fluorescence
Indeterminate from visual assessment alone, likely Faint to Medium
Inclusions
Feathers, carbon spots, and internal fracture lines visible
Blemishes
Surface naturals, trigons potentially present, and rough matrix attachments
Origin
Alluvial deposit or primary kimberlite/pegmatite pipe origin
Treatment Detection
No signs of artificial treatment; completely natural state
Estimated Value
Varies significantly depending on true mineral composition (diamond vs. beryl), estimated raw specimen value ranging from $500 to $2,000
Certification Estimate
GIA would likely issue an identification report rather than a standard grading report for rough material
Investment Potential
Collector's specimen value rather than standard investment-grade polished diamond

Setting Suggestions
Wire-wrapped pendant or bespoke organic prong setting to preserve the raw aesthetic
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh acids or ultrasonic cleaners due to internal fractures
Interesting Facts
Natural blue diamonds owe their color to trace amounts of boron trapped within the carbon crystal lattice during formation
