Natural rough mineral crystal (likely quartz or similar silicate rather than gem-quality diamond based on crystal habit and striations)
Natural rough mineral crystal (likely quartz or similar silicate rather than gem-quality diamond based on crystal habit and striations) · Rough uncut crystal / Irregular elongated fragment
Uncut / Raw (Not applicable for standard faceted cut grades) Cut
Carat
Estimated 2.0 to 3.5 carats equivalent based on visual dimensions
Color
Colorless to very faint brown/grey tint
Clarity
Included (I1-I2 equivalent due to internal fractures and inclusions)
Shape
Rough uncut crystal / Irregular elongated fragment
Overall Assessment
The specimen in the image appears to be a raw, uncut mineral crystal rather than a faceted diamond, displaying natural striations and internal structural fractures typical of unprocessed rough minerals.
Cut Quality
Uncut / Raw (Not applicable for standard faceted cut grades)
Brilliance
Low due to lack of standard facet angles and internal fracturing
Fire
Minimal due to raw crystal surface and lack of dispersion-optimized facets
Scintillation
Poor, lacking standard facet reflections and alternating light/dark patterns
Proportions
Natural uncut proportions with elongated crystal habit
Symmetry
Natural asymmetric crystal growth
Polish
Raw natural crystal faces showing striations, no artificial polish
Fluorescence
Cannot be definitively determined from visual image alone (likely None to Faint)
Inclusions
Internal feather fractures, granular inclusions, and growth channels
Blemishes
Natural surface etching, irregularities, and rough unpolished faces
Origin
Natural geological formation from pegmatite or hydrothermal veins
Treatment Detection
No indications of artificial treatments; appears entirely natural and untreated
Estimated Value
Nominal value as a mineral specimen rather than a faceted gem
Certification Estimate
Not typically certified by GIA/AGS as a diamond; would require mineralogical identification (e.g., Raman spectroscopy)
Investment Potential
Low investment potential; valued primarily for educational or mineral specimen collections
Similar Diamonds
Comparable to low-grade industrial diamond rough or raw quartz crystal specimens
Setting Suggestions
Wire-wrapped pendant or organic raw stone bezel setting
Care & Maintenance
Store separately to prevent scratching other stones; avoid harsh chemical cleaners and ultrasonic baths if inclusions are weak
Interesting Facts
Raw mineral specimens show the natural growth habits and crystal faces before human intervention and faceting
