Rough Crystal / Step Cut Hybrid
Overall Assessment
An interesting raw mineral specimen with pronounced optical effects and internal flaws, best suited for mineral collections rather than jewelry.
Cut Quality
Fair to Poor (Custom hand-ground or raw crystal form)
Brilliance
Low due to internal fracturing and opacity
Fire
High surface dispersion visible as rainbow iridescence
Scintillation
Limited, scattered light return
Proportions
Non-standard, heavy depth with distorted pavilion
Symmetry
Asymmetrical, irregular crystal habit
Polish
Uneven, partial polish with natural rough faces
Fluorescence
Strong spectral iridescence under ambient light
Inclusions
Significant internal fractures, feathering, and mineral deposits
Blemishes
Surface chips, natural growth lines, and rough patches
Origin
Natural rough mineral deposit (Pegmatite pocket)
Treatment Detection
Potential surface coating (aura quartz treatment) or natural thin-film interference
Estimated Value
$50 - $200 USD as a mineral specimen
Certification Estimate
Gemological Institute of America (GIA) - Identification Report (non-gem grade)
Investment Potential
Low for resale, high for mineral collection/educational value
Similar Diamonds
None (this specimen visually resembles treated quartz or raw beryl rather than gemstone-quality diamond)
Setting Suggestions
Wire-wrapped or custom bezel setting for display mineral specimens
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaning, and impact due to high internal fracture density
