Natural Rough Diamond (Uncut)
Natural Rough Diamond (Uncut) · Natural Elongated Macle/Crystalline Fragment
None (Natural Rough) Cut
Carat
Estimated 3.0 to 5.0 carats based on finger scale
Color
Light Yellow to Brownish Tint (Estimated K-M range)
Clarity
Included (I1-I2 equivalent in rough state)
Shape
Natural Elongated Macle/Crystalline Fragment
Overall Assessment
A genuine natural rough diamond macle/fragment with significant internal inclusions and a yellowish-brown tint, suitable for collection or industrial use rather than high-end jewelry faceting.
Cut Quality
None (Natural Rough)
Brilliance
Low (Surface reflections only)
Fire
None (Requires faceting to display dispersion)
Scintillation
Low (Minimal light play due to lack of facets)
Proportions
Elongated natural form, approximately 3:1 length-to-width ratio
Symmetry
Low (Natural asymmetric crystal structure)
Polish
None (Natural crystal faces with growth lines)
Fluorescence
Indeterminate without UV source
Inclusions
Visible internal fractures (feathers), cloudy twinning planes, and mineral inclusions
Blemishes
Natural trigons (triangular growth pits), surface abrasions, and stepped growth faces
Origin
Likely African (DRC or Sierra Leone) based on morphology
Treatment Detection
None apparent; looks completely natural and untreated
Estimated Value
$1,500 - $3,500 USD (Specimen/Industrial value)
Certification Estimate
GIA Rough Diamond Rough Analysis Report (Estimated K-M color, I1 clarity)
Investment Potential
Low to Moderate; value primarily resides in potential for faceting into smaller stones
Similar Diamonds
Uncut alluvial diamonds from Central African riverbeds
Setting Suggestions
Rough diamond specimen setting or custom organic 'claws' in yellow gold
Care & Maintenance
Protect from sharp impacts; rough edges can catch on fabrics and harbor oils
Interesting Facts
The surface displays 'trigons', which are microscopic triangular growth structures unique to diamond crystals.
