Overall Assessment
This specimen is not a faceted diamond. It is a rough, transparent material, likely glass, quartz, or a synthetic resin, characterized by high dispersion and significant internal fracturing.
Cut Quality
Uncut / Rough
Brilliance
Low (significant light leaking due to lack of facets)
Fire
High (exhibiting significant thin-film interference or dispersion colors)
Scintillation
Poor
Proportions
N/A - Rough specimen
Symmetry
Poor / Asymmetrical
Polish
Natural / N/A
Fluorescence
Indeterminate; specimen shows high spectral dispersion
Inclusions
Heavy internal fracturing, cleavage planes, and step-like growth patterns
Blemishes
Rough, jagged surface textures and sharp edges
Origin
Likely synthetic or man-made mineral/plastic due to fracture pattern
Treatment Detection
N/A - Appears to be an untreated base material
Estimated Value
$5 - $50 (Decorative/Curiosity value)
Certification Estimate
Unlikely to be graded by GIA or IGI as a diamond; GRS for specimen ID
Investment Potential
None
Similar Diamonds
Rough Herkimer Diamond (Quartz) or glass cullet
Setting Suggestions
Wire wrapping or custom resin encasement
Care & Maintenance
Avoid harsh chemicals and high heat; likely susceptible to scratches
Interesting Facts
The specimen exhibits 'iridescence' similar to oil on water, suggesting thin films of air within fractures.
