Overall Assessment
This specimen appears to be either a low-quality rough diamond or a piece of industrial glass/quartz based on the fracture patterns and surface texture.
Cut Quality
Uncut/Raw
Brilliance
Low (Surface diffusion prevents light return)
Fire
Moderate (Visible spectral colors suggest thin-film interference)
Scintillation
Low (Limited to surface reflection)
Proportions
N/A (No geometric facets)
Symmetry
N/A (Asymmetric rough)
Polish
N/A (Natural/Raw surface)
Fluorescence
Not observable under white light
Inclusions
Internal fractures, needles, and possibly fluid inclusions
Blemishes
Surface percussion marks and scratches
Origin
Potential secondary deposit (alluvial) if natural stone
Treatment Detection
No obvious signs of treatment; appears in raw state
Estimated Value
Low (Until verified as diamond and weight determined)
Certification Estimate
GIA (Rough Diamond Report) if proven natural
Investment Potential
Low (Requires precision cutting to gain significant value)
Similar Diamonds
Uncut Boart or industrial-grade rough
Setting Suggestions
Prong setting for rough stones or protective bezel
Care & Maintenance
Ultrasonic cleaners should be avoided due to visible internal fractures
Interesting Facts
Thin-film interference across surface fractures creates rainbow effects often mistaken for fire.
