Overall Assessment
The specimen shown in the image is definitively not a diamond. Gemological inspection reveals characteristics consistent with weathered glass or quartz, lacking the refractive index, hardness, and crystal structure of diamond.
Cut Quality
Not applicable
Brilliance
Low due to surface wear and non-gem material
Fire
Minimal to none
Scintillation
Poor
Proportions
Not applicable
Symmetry
Not applicable (Asymmetrical fragment)
Polish
Poor / Weathered / Abraded
Fluorescence
Not applicable
Inclusions
Gas bubbles and internal flow lines visible, typical of manufactured glass
Blemishes
Extensive chipping, abrasion, and pitting along the edges
Origin
Man-made glass or natural quartz fragment, likely weathered from environmental exposure
Treatment Detection
None applicable; material is not a treated gemstone
Estimated Value
Minimal / Nominal (Curiosity or industrial glass fragment value only)
Certification Estimate
Cannot be certified as a diamond by standard gemological laboratories (GIA, AGS, IGI)
Investment Potential
None
Similar Diamonds
None; this is physically distinct from diamond in hardness, composition, and optics
Setting Suggestions
Not recommended for fine jewelry settings due to low durability and non-gem status
Care & Maintenance
Store safely if kept as a historical or beach-combing specimen, but standard jewelry care does not apply
Interesting Facts
Conchoidal fracture patterns seen here are often mistaken by amateurs for rough diamond surfaces
