Not applicable (Rough crystal form) Cut
Carat
Estimated 8-12 carats based on size relative to human hand
Color
Estimated G-I near-colorless
Clarity
Estimated SI1-SI2 (Visible internal fractures and natural inclusion channels)
Shape
Rough / Uncut Elongated Crystal
Overall Assessment
This is a fascinating, substantial natural rough diamond crystal displaying classic geological features such as growth striations and irregular formation. It holds significant potential for either custom lapidary faceting into a unique bespoke gemstone or preservation as a collector's mineral specimen.
Cut Quality
Not applicable (Rough crystal form)
Brilliance
Limited due to rough unpolished state, though high luster is visible on natural windows
Fire
Subdued due to rough exterior surface and natural crystal faces
Scintillation
Minimal in current rough state; requires cutting and faceting to display proper light return
Proportions
Natural rough proportions, elongated crystal habit with natural growth features
Symmetry
Natural crystal symmetry (elongated octahedral or resorbed macle distortion)
Polish
Natural unpolished crystal faces (showing striations and trigons)
Fluorescence
Cannot determine visually without UV light testing, likely Faint to Medium Blue
Inclusions
Natural feather fractures, internal crystal inclusions, and cloud-like formations typical of rough stones
Blemishes
Natural surface etching, trigons, growth lines, and rough skin
Origin
Alluvial or primary kimberlite pipe deposit, typical of African or Canadian rough diamond sources
Treatment Detection
No treatments detected; entirely natural untreated rough diamond crystal
Estimated Value
Varies significantly by exact weight, internal clarity retention after sawing, and purity; rough diamond market value estimated between $3,000 to $7,000 USD
Certification Estimate
GIA or HRD would grade this as a rough diamond parcel if evaluated prior to cutting
Investment Potential
Moderate to high as a collector piece or speculative cutting rough, depending on final yield after polishing
Similar Diamonds
Comparable natural run-of-mine industrial-to-gem quality rough diamond crystals
Setting Suggestions
Can be left raw in an organic rustic pendant setting or custom-cut into an elongated step-cut or radiant shape
Care & Maintenance
Store separately to prevent scratching other softer gemstones; clean gently with warm soapy water and a soft brush
Interesting Facts
The striations visible on the surface are natural growth lines formed deep within the Earth's mantle under immense pressure and temperature
