Natural diamond crystal (rough/uncut)
Natural diamond crystal (rough/uncut) · Rough, irregular octahedron fragment / cleavage piece
Not applicable (Rough stone, unpolished state) Cut
Carat
Estimated 2.0 - 3.5 carats based on visual proportions
Color
Near-colorless to faint tint (approx. G-I range)
Clarity
Included (I1-I2) due to prominent internal fractures, feathers, and potential inclusions
Shape
Rough, irregular octahedron fragment / cleavage piece
Overall Assessment
This is a raw, natural diamond crystal fragment displaying characteristic cleavage planes and internal fractures. While not suitable for high-end traditional jewelry in its current state, it possesses a unique organic charm suitable for raw gemstone jewelry or mineral collections.
Cut Quality
Not applicable (Rough stone, unpolished state)
Brilliance
Low to moderate due to rough surfaces and internal fractures scattering light
Fire
Limited dispersion visible internally through transparent cleavage windows
Scintillation
Minimal play of light due to lack of standard facet patterns
Proportions
Uncut crystal; natural proportions defined by crystal growth rather than gemological cutting standards
Symmetry
Asymmetrical due to natural crystalline habit and cleavage
Polish
Natural rough crystal faces (trigons/striations potentially present) and fractured surfaces
Fluorescence
Indeterminate from photo, often medium to strong blue in natural rough diamonds under UV
Inclusions
Significant internal feathers, cleavage planes, and dark mineral spots visible internally
Blemishes
Natural surface irregularities, rough edges, and abrasion marks from extraction
Origin
Natural alluvial or primary kimberlite deposit origin
Treatment Detection
No obvious signs of artificial treatment; appears completely untreated and natural
Estimated Value
Modest value as a specimen or industrial/low-grade gem material, roughly $100 - $300 depending on exact weight and cutting potential
Certification Estimate
GIA (Gemological Institute of America) as a rough diamond report or origin report
Investment Potential
Low investment potential for resale as a gem; primarily of interest to collectors of minerals or bespoke jewelry artisans
Similar Diamonds
Other unassorted industrial or lower-gem quality rough diamond parcels
Setting Suggestions
Wire-wrapped rough stone pendant, organic bezel setting, or custom raw-gem jewelry design
Care & Maintenance
Avoid harsh impacts which could exploit existing internal cleavage planes and cause breakage; clean with mild soapy water and a soft brush
Interesting Facts
Rough diamonds often exhibit curved crystal faces and characteristic triangular growth marks called trigons on their octahedral faces
