Not a diamond; this is a piece of blue glass, likely industrial or decorative cullet.
Not a diamond; this is a piece of blue glass, likely industrial or decorative cullet. · Irregular / Raw fragment
Not applicable (uncut raw fragment) Cut
Carat
Not applicable for glass (estimated weight via volume would be non-gemological)
Color
Vivid Blue (synthetic coloring)
Clarity
Included (contains prominent internal gas bubbles and flow lines characteristic of glass)
Shape
Irregular / Raw fragment
Overall Assessment
This specimen is definitively identified as blue glass rather than a diamond or gemstone. The visible gas bubbles and amorphous fracture patterns eliminate any possibility of it being a diamond, synthetic diamond, or crystalline mineral.
Cut Quality
Not applicable (uncut raw fragment)
Brilliance
Low to moderate, typical of vitreous materials
Fire
Very low dispersion compared to diamond or moissanite
Scintillation
Poor, lacking faceted optical return
Proportions
Non-standard amorphous slab
Symmetry
Asymmetrical
Polish
Rough fractured surfaces
Fluorescence
None to inert
Inclusions
Prominent spherical gas bubbles visible throughout the interior matrix
Blemishes
Surface scratches, abrasions, and cooling stress lines
Origin
Man-made glass manufacturing facility
Treatment Detection
Colored glass artifact
Estimated Value
Nominal decorative or craft value (under $5 USD)
Certification Estimate
Cannot be certified by gemological grading labs like GIA or IGI as a gemstone
Investment Potential
None
Similar Diamonds
None (diamonds do not form gas bubbles or amorphous shards)
Setting Suggestions
Wire-wrapping or decorative craft settings if used for display
Care & Maintenance
Standard cleaning with mild soap and warm water; avoid harsh impacts as glass is brittle
Interesting Facts
The presence of rounded internal gas bubbles is a definitive diagnostic indicator distinguishing glass from natural crystalline gemstones or synthetic diamonds.
