Natural rough mineral crystal (likely quartz or similar crystalline matrix, pending professional gemological testing)
Natural rough mineral crystal (likely quartz or similar crystalline matrix, pending professional gemological testing) · Uncut raw crystal fragment / Irregular freeform
Not applicable (raw, uncut specimen) Cut
Carat
Estimated 3.5 to 5.0 carats based on relative finger scale
Color
Near-colorless to transparent with local dark matrix staining
Clarity
Included / Heavily included with internal fractures and surface matrix pockets
Shape
Uncut raw crystal fragment / Irregular freeform
Overall Assessment
An interesting raw crystal fragment held between fingers, showing natural growth features and surface mineral staining. Professional laboratory testing (such as refractometer or Raman spectroscopy) is recommended to confirm the exact mineral species.
Cut Quality
Not applicable (raw, uncut specimen)
Brilliance
Low to moderate vitreous luster, primarily dependent on raw surface reflections
Fire
Minimal dispersion due to lack of faceted geometry
Scintillation
Poor, limited to flash reflection off smooth natural cleavage or fracture planes
Proportions
Irregular raw specimen; traditional proportions (table, depth, angles) do not apply
Symmetry
Natural asymmetric crystal growth
Polish
Raw, unpolished surface showing natural crystal growth lines and conchoidal fracture patterns
Fluorescence
Indeterminate without UV lamp testing
Inclusions
Subsurface fractures, veining, and dark particulate mineral inclusions
Blemishes
Surface pits, natural cavities, and adhering host rock matrix
Origin
Alluvial or primary pegmatite/hydrothermal mineral deposit origin
Treatment Detection
No obvious signs of artificial enhancement or treatment; appears completely untreated
Estimated Value
Nominal specimen or mineral collector value (low, pending exact mineral identification)
Certification Estimate
Standard gemological identification report from GIA or local gem lab identifying the mineral species
Investment Potential
Low investment value; primarily suited for mineral specimen collectors or educational display
Similar Diamonds
Rough diamond crystals of industrial or low gem quality, though visual appearance strongly suggests quartz crystal or beryl rather than diamond
Setting Suggestions
Wire-wrapped pendant setting or custom organic prong mount to preserve the raw, natural aesthetic
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to internal fractures
Interesting Facts
Raw mineral specimens showcase the natural geological formation processes before human intervention and facet cutting
