Non-diamond (Likely Glass, Slag, or Industrial byproduct)
Non-diamond (Likely Glass, Slag, or Industrial byproduct) · Irregular / Rough Uncut
Poor / None (Uncut material) Cut
Carat
Estimated 10-20 carats based on visual size relative to background textures
Color
Colorless / Transparent with heavy internal iridescence
Clarity
I3 (Highly included / Fractured)
Shape
Irregular / Rough Uncut
Overall Assessment
This specimen is not a diamond. The conchoidal (shell-like) fracture patterns and the flow-like internal structures are diagnostic of glass or a similar amorphous solid rather than a crystalline gemstone like diamond.
Cut Quality
Poor / None (Uncut material)
Brilliance
Low (Internal light scatter rather than refractive return)
Fire
High internal iridescence (thin-film interference) rather than true refractive fire
Scintillation
None (No faceted surfaces to create sparkle)
Proportions
N/A (Non-geometric)
Symmetry
Poor (Asymmetrical)
Polish
Poor (Naturally rough or broken surfaces)
Fluorescence
Cannot be determined without UV light, but likely inert
Inclusions
Extensive internal fracturing, fluid-like flow lines, and conchoidally fractured edges
Blemishes
Heavy surface scratching and impact marks consistent with glass or brittle minerals
Origin
Likely industrial waste or glass fragment; certainly not a natural diamond crystal
Treatment Detection
None detected; material appears to be a raw byproduct
Estimated Value
$1 - $10 (Decorative or mineralogical value only)
Certification Estimate
Unlikely to be graded by GIA or IGI as a gemstone; would likely be rejected as non-diamond
Investment Potential
None
Similar Diamonds
None (This specimen lacks the cubic crystal structure of a diamond)
Setting Suggestions
Not suitable for traditional jewelry settings; perhaps a wire-wrap if kept as a curiosity
Care & Maintenance
Handle with care as glass-like materials can be sharp and prone to further shattering
Interesting Facts
The rainbow colors seen are likely due to 'thin-film interference' within internal cracks rather than diamond dispersion
