Natural rough mineral crystal (likely beryl, quartz, or another silicate rather than true diamond based on the prismatic crystal habit and striations, but evaluated under diamond criteria)
Natural rough mineral crystal (likely beryl, quartz, or another silicate rather than true diamond based on the prismatic crystal habit and striations, but evaluated under diamond criteria) · Rough uncut prismatic crystal
Not applicable (uncut rough crystal) Cut
Carat
Estimated 8-12 carats based on rough crystal dimensions
Color
Near colorless to very light tint
Clarity
Included (I1-I2 equivalent due to internal fracture lines and striations)
Shape
Rough uncut prismatic crystal
Overall Assessment
A fascinating raw, uncut mineral specimen with visible natural striations and internal growth features, holding value primarily as a natural crystal specimen rather than a faceted gemstone.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Low due to lack of faceting and rough surface condition
Fire
Minimal dispersion due to raw crystalline state
Scintillation
Absent prior to cutting and faceting
Proportions
Elongated prismatic crystal habit
Symmetry
Natural crystal symmetry (prismatic elongation with striations)
Polish
Natural crystal faces (unpolished)
Fluorescence
Cannot be reliably determined without UV testing (estimated None to Faint)
Inclusions
Heavy internal feathering, growth lines, and cleavage planes visible
Blemishes
Natural surface etching, striations, and surface fractures
Origin
Natural alluvial or pegmatite deposit
Treatment Detection
No signs of enhancement or artificial treatment detected; completely untreated natural state
Estimated Value
Nominal value as a mineral specimen rather than a cut gemstone
Certification Estimate
Gemological institute report for rough identification (GIA or local lab)
Investment Potential
Collector specimen value rather than commercial diamond investment
Similar Diamonds
Comparable rough diamond or gem-quality raw mineral crystals
Setting Suggestions
Wire-wrapped or raw organic bezel settings to preserve the natural crystal form
Care & Maintenance
Store carefully to avoid impacts along natural cleavage lines and avoid harsh chemicals
