Not Applicable (Rough Stone) Cut
Carat
Estimated 3.5 to 4.5 carats
Color
Near Colorless (Estimated G-I range)
Clarity
Included (Estimated SI1-SI2 range due to natural internal feathers and inclusions)
Shape
Rough / Uncut Elongated Crystal
Overall Assessment
An interesting, substantial natural rough diamond crystal displaying characteristic growth lines and surface textures, offering potential for a custom-cut faceted gemstone or retention as a unique mineral specimen.
Cut Quality
Not Applicable (Rough Stone)
Brilliance
Low to Moderate due to rough, unpolished exterior surfaces
Fire
Minimal dispersion visible through rough exterior faces
Scintillation
Limited flash due to lack of faceted geometry
Proportions
Natural elongation, no standard table or depth proportions applicable
Symmetry
Natural Asymmetric Crystal Formation
Polish
Natural Unpolished Surface with Growth Lines (Trigons or Etch Channels)
Fluorescence
Indeterminate from visual inspection (typically requires UV testing)
Inclusions
Natural feathers, internal stress fractures, and mineral inclusions visible
Blemishes
Natural surface etch marks, striations, and irregular growth features
Origin
Likely alluvial or primary kimberlite/lamproite deposit (African or Canadian origin typical for such morphology)
Treatment Detection
None detected (completely untreated natural rough crystal)
Estimated Value
Depends heavily on cutting yield; rough specimen estimated between $1,500 - $3,000 wholesale
Certification Estimate
GIA or similar major lab for a rough weight certificate if evaluated in raw form
Investment Potential
Moderate; value is speculative based on potential yield if cut and polished
Similar Diamonds
Other alluvial rough diamond octahedrons and elongated crystal specimens
Setting Suggestions
Raw crystal pendant setting in yellow gold or platinum to preserve its organic, unworked aesthetic
Care & Maintenance
Store separately to avoid scratching other jewelry; clean with mild soapy water and a soft brush
Interesting Facts
Elongated rough crystals often exhibit natural striations and growth lines formed deep within the Earth's mantle under extreme pressure
