Not a diamond; likely glass, quartz, or synthetic imitation containing prominent gas bubbles characteristic of glass.
Not a diamond; likely glass, quartz, or synthetic imitation containing prominent gas bubbles characteristic of glass. · Irregular raw fragment / rough amorphous piece with no standard diamond cut.
Poor / Uncut raw fragment Cut
Carat
Not applicable for diamond valuation due to material identification, but visual mass appears roughly 3-5 carats equivalent if solid.
Color
Colorless / Clear
Clarity
Included heavily with numerous spherical gas bubbles and internal flow lines.
Shape
Irregular raw fragment / rough amorphous piece with no standard diamond cut.
Overall Assessment
Visual inspection reveals internal rounded gas bubbles and conchoidal fracture patterns typical of glass or slag, confirming this specimen is definitely not a diamond.
Cut Quality
Poor / Uncut raw fragment
Brilliance
Low to moderate vitreous luster, lacks diamond adamantine brilliance.
Fire
Minimal to none (glass lacks the high dispersion of diamond or moissanite).
Scintillation
Poor, lacks facet-based light return.
Proportions
Not applicable (no standard pavilion, crown, or table proportions)
Symmetry
Asymmetrical raw fragment
Polish
Unpolished / Raw fracture surfaces with conchoidal texture
Fluorescence
Unknown without UV testing, likely none to inert.
Inclusions
Abundant rounded gas bubbles visible internally, characteristic of man-made glass.
Blemishes
Surface scratches, chips, and irregular fracture lines.
Origin
Man-made glass or natural quartz pebble / slag.
Treatment Detection
N/A
Estimated Value
Nominal value (decorative glass or mineral specimen value only, essentially zero gem value).
Certification Estimate
Not certifiable as a diamond by major labs such as GIA, AGS, or IGI.
Investment Potential
None.
Similar Diamonds
None, as this material is not a diamond.
Setting Suggestions
Not recommended for fine jewelry settings due to softness and fragile nature.
Care & Maintenance
Standard gentle cleaning with mild soapy water if kept as a mineral or glass specimen.
Interesting Facts
The presence of spherical gas bubbles is a definitive diagnostic indicator that this material is glass rather than diamond or quartz.
