I3 (Included / Industrial Grade)
Shape
Rough / Uncut Elongated Crystal
Overall Assessment
This is a natural rough diamond specimen of industrial or specimen quality. It lacks the clarity and transparency required for a high-value faceted gem but serves as an excellent example of macro-crystalline diamond growth.
Cut Quality
Uncut / Raw
Brilliance
Low (Lustrous but lacks facets for light return)
Fire
None (Requires faceting for dispersion)
Scintillation
Low (Surface reflections only)
Proportions
Elongated habit, irregular cleavage faces
Symmetry
N/A (Asymmetrical rough)
Polish
N/A (Natural skin)
Fluorescence
Cannot be determined without UV light
Inclusions
Extensive internal twinning wisps, dark mineral inclusions (possibly graphite or sulfide), and deep fractures
Blemishes
Surface percussion marks, frosted skin, and rough cleavage edges
Origin
Likely Alluvial or Primary deposit (Mina-style rough)
Treatment Detection
None apparent; looks completely natural
Estimated Value
$50 - $150 per carat (Specimen or Industrial value)
Certification Estimate
GIA (Rough Diamond Report)
Investment Potential
Low (Lacks gem-quality clarity for high-end investment)
Similar Diamonds
Similar to 'Bort' or industrial grade macles and elongated roughs
Setting Suggestions
Wire wrap, tension setting for raw stones, or display specimen
Care & Maintenance
Avoid ultrasonic cleaners due to fractures; clean with soft brush and warm water
Interesting Facts
The elongated shape suggests this stone likely grew under high pressure and temperature but suffered significant stress during its trek to the surface.
