Not a diamond; this is heavily worn or fractured glass, possibly a melted bottle neck or slag glass.
Not a diamond; this is heavily worn or fractured glass, possibly a melted bottle neck or slag glass. · Irregular, melted, and unshaped fragment
Poor / Uncut and unpolished amorphous material Cut
Carat
Not applicable (not a gemstone)
Color
Colorless to pale tint due to impurities
Clarity
I3 / heavily flawed with numerous internal bubbles, scratches, and stress fractures
Shape
Irregular, melted, and unshaped fragment
Overall Assessment
Visual examination confirms this specimen is vitreous glass rather than a diamond or other precious gemstone. It lacks the crystalline structure, hardness, and optical properties characteristic of diamond.
Cut Quality
Poor / Uncut and unpolished amorphous material
Brilliance
Minimal to none due to lack of optical facets and surface degradation
Fire
Negligible dispersion
Scintillation
None
Proportions
Non-standard, irregular amorphous shape
Symmetry
None (completely asymmetrical)
Polish
Poor (abraded, rough surface with flow lines and wear)
Fluorescence
Unknown without UV testing
Inclusions
Abundant gas bubbles, striations, and internal fractures typical of manufactured glass
Blemishes
Heavy surface scratching, chipping, abrasion marks, and pitting
Origin
Man-made glass artifact
Treatment Detection
Not applicable; object is vitreous glass rather than crystalline diamond
Estimated Value
Zero monetary value as a gemstone (scrap/curio value only)
Certification Estimate
Cannot be certified by any standard gemological laboratory (GIA, AGS, IGI) as a gemstone
Investment Potential
None
Similar Diamonds
None (no gemological similarity)
Setting Suggestions
Not recommended for jewelry setting due to softness, fragility, and lack of gemological value
Care & Maintenance
Handle with care to avoid cuts from sharp edges; clean with mild soap and water if kept as a curiosity
Interesting Facts
The object's fluid-like neck shape and internal gas bubbles strongly indicate it is a piece of historical or discarded glassware that has been deformed or broken.
