Natural rough diamond crystal
Natural rough diamond crystal · Rough elongated crystal (octahedral/trigonal habit influenced)
Not applicable (Rough, unpolished crystal state) Cut
Carat
Estimated 3.5 to 4.5 carats based on visual scale and density
Color
Near-colorless to very faint yellowish tint (approx. G-J range)
Clarity
Included (I1-I2 estimated due to visible internal fracturing and feather inclusions)
Shape
Rough elongated crystal (octahedral/trigonal habit influenced)
Overall Assessment
An interesting, sizable natural rough diamond crystal in a raw state, showing classic crystal growth markings and internal natural fractures, ideal for mineral collectors or custom organic jewelry design.
Cut Quality
Not applicable (Rough, unpolished crystal state)
Brilliance
Low due to rough, unpolished surface scattering light
Fire
Minimal visible fire in current rough state
Scintillation
Poor due to lack of facets and rough exterior
Proportions
Natural rough proportions, asymmetrical elongated morphology
Symmetry
Natural crystal symmetry showing typical growth lines and distortion
Polish
None (natural crystal faces/etching present)
Fluorescence
Indeterminate from visual assessment alone, likely inert to moderate blue
Inclusions
Internal cleavage planes, feathers, and potential mineral inclusions (e.g., graphite or sulfide specks)
Blemishes
Natural trigons (growth triangles), surface etching, and rough skin textures
Origin
Likely alluvial or primary kimberlitic deposit (African or Russian origin)
Treatment Detection
No signs of artificial treatment; completely natural rough specimen
Estimated Value
$500 - $1,500 depending on cutting yield and final polished outcome
Certification Estimate
GIA rough diamond evaluation or local gemological lab certificate upon cutting
Investment Potential
Moderate speculative value as a collector's mineral specimen; higher risk if intended for cutting without precision planning
Similar Diamonds
Other natural unpolished octahedral or elongated rough diamond crystals of comparable size
Setting Suggestions
Can be set raw in an organic, rustic, or wire-wrapped pendant design using yellow gold or platinum
Care & Maintenance
Store separately to avoid scratching other gemstones; clean gently with warm soapy water and a soft brush
Interesting Facts
The specimen displays natural triangular growth features known as trigons on its faces, typical of rough diamond dissolution and growth histories
