Natural (Rough / Uncut)
Natural (Rough / Uncut) · Rough crystal fragment / Irregular octahedral or elongated shard
Not applicable (Raw, unpolished rough stone) Cut
Carat
Estimated 2.0 to 3.5 carats based on visual proportions and scale against fingertips
Color
Near colorless to faint brown/yellow tint (approx. K-M equivalent or rough equivalent)
Clarity
Included (I1-I2 equivalent due to prominent internal fractures, feathers, and dark inclusions visible)
Shape
Rough crystal fragment / Irregular octahedral or elongated shard
Overall Assessment
This is an intriguing, completely natural rough diamond specimen. While its internal inclusions and fractures limit its high-jewelry potential in its current state, it possesses great organic charm and could yield an interesting faceted stone or be set raw in unique artisan jewelry.
Cut Quality
Not applicable (Raw, unpolished rough stone)
Brilliance
Low to moderate due to raw, unpolished surfaces and internal fractures scattering light
Fire
Minimal visible dispersion in its current rough, unfaceted state
Scintillation
Poor sparkle; raw surface planes reflect light diffusely rather than creating distinct flashes
Proportions
Uncut crystal morphology; depth and table percentages do not apply
Symmetry
Natural crystal symmetry, highly irregular due to natural cleavage and fracturing
Polish
Natural crystal faces (trigons potentially present) and fractured surfaces; no human polish
Fluorescence
Indeterminate without UV testing equipment, likely faint blue or none
Inclusions
Large feathers, internal cleavages, dark mineral crystals, and cloud-like clusters visible
Blemishes
Natural surface etch channels, triangular growth marks (trigons), and rough fractured edges
Origin
Natural alluvial or primary kimberlite deposit origin (African, Canadian, or Russian provenance possible)
Treatment Detection
No signs of artificial treatment; completely natural untreated rough diamond
Estimated Value
Modest collector or industrial/jewelers' rough value, roughly $200 - $600 depending on cutting potential
Certification Estimate
GIA or similar major lab would issue a rough diamond report or origin certificate rather than a cut-stone grading report
Investment Potential
Low investment liquidity as a rough stone unless cut and polished by a master lapidary to maximize yield and clarity
Similar Diamonds
Other natural rough diamond crystals, slice diamonds, or uncut crystal pendant stones
Setting Suggestions
Best suited for custom raw/uncut diamond jewelry, bezel settings in yellow or rose gold to embrace the organic aesthetic
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to existing internal feathers and fractures that could propagate
Interesting Facts
Rough diamonds retain the ancient geological journey they took from the Earth's mantle, often featuring natural growth features like triangular etchings called trigons
