Natural rough diamond crystal
Natural rough diamond crystal · Rough crystal / Uncut octahedral or irregular elongation
Not applicable (Rough, uncut specimen) Cut

Carat
Estimated 3.50 to 5.00 carats based on visual scale against fingers
Color
Near-colorless to faint tint (approx. G-J range)
Clarity
Included (approx. I1 to I2) due to visible dark mineral inclusions and feathers
Shape
Rough crystal / Uncut octahedral or irregular elongation
Overall Assessment
An intriguing natural rough diamond crystal showing characteristic surface features, raw texture, and internal inclusions, holding great potential if faceted by an expert master cutter.
Cut Quality
Not applicable (Rough, uncut specimen)
Brilliance
Low to moderate in rough form; will increase significantly upon cutting and polishing
Fire
Subdued in rough state; dependent on final pavilion angles and polish
Scintillation
Minimal play of light currently due to rough, unpolished surface facets
Proportions
Natural rough proportions, heavily dependent on future cutting plan
Symmetry
Natural asymmetrical crystal growth formation
Polish
Natural crystalline surface texture (trigons and striations typical of rough diamonds)
Fluorescence
Indeterminate from visual inspection alone (typically tested via UV lamp)
Inclusions
Visible dark mineral inclusions, internal fractures (feathers), and cloudiness
Blemishes
Natural surface pitting, rough skin, and possible abrasions from extraction
Origin
Alluvial or primary kimberlite pipe deposit (exact mine unknown without internal inclusion analysis)
Treatment Detection
No treatments detected; appears entirely untreated in natural rough state
Estimated Value
Varies widely depending on yield after cutting, rough industrial to gem-grade value ranging from hundreds to a few thousand dollars
Certification Estimate
GIA or similar major lab upon submission for professional grading post-cut
Investment Potential
Speculative, as value depends entirely on the potential polished yield and master cutting loss

Setting Suggestions
Can be mounted raw in organic or rustic bespoke jewelry designs, or cut into a modern brilliant shape for standard settings
Care & Maintenance
Store separately to prevent scratching other softer gemstones, clean with mild soapy water and a soft brush
Interesting Facts
Rough diamonds like this have traveled billions of years from the Earth's mantle via explosive volcanic kimberlite eruptions
