Uncut / Raw crystal with irregular elongated shape
Overall Assessment
An intriguing natural rough diamond specimen showing classic unpolished characteristics, surface etching, and inclusions, making it suitable for mineral collectors or custom organic jewelry design.
Cut Quality
Not applicable (Rough, unpolished crystal specimen)
Brilliance
Low to moderate due to rough unpolished exterior and internal inclusions
Fire
Minimal dispersion visible on the unfaceted surface
Scintillation
Limited, reflecting light irregularly from natural crystal faces and etched channels
Proportions
N/A for cut stones; irregular natural crystal habit with uneven thickness
Symmetry
Asymmetrical, typical of natural alluvial or primary deposit rough crystal formation
Polish
Natural rough surface textures, featuring growth lines, trigons, and natural etch channels
Fluorescence
Unable to determine without UV testing; likely None to Moderate
Inclusions
Multiple visible dark mineral inclusions, cloud patches, and internal fractures
Blemishes
Natural surface etchings, pitting, and irregular growth features
Origin
Likely alluvial deposit origin (riverbed or marine) given the smoothed yet etched natural surface textures
Treatment Detection
No visible signs of artificial treatments; appears entirely natural and untreated
Estimated Value
$300 - $800 depending on cutting yield potential and industrial vs. gem grade classification
Certification Estimate
GIA or local gemological laboratory providing a rough diamond report
Investment Potential
Low as a polished investment stone, but moderate collector appeal as a raw mineral specimen
Similar Diamonds
Comparable to industrial or lower-gem quality alluvial rough diamonds from African or South American deposits
Setting Suggestions
Best preserved as a raw mineral specimen in a custom organic bezel or wire-wrap setting
Care & Maintenance
Store separately to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Raw diamond crystals often display natural growth markings called trigons on their octahedral faces
