Not a diamond; this is glass (imitation) due to the presence of numerous gas bubbles.
Not a diamond; this is glass (imitation) due to the presence of numerous gas bubbles. · Oval Cabochon
Fair to Poor (irregular cabochon polish and shape) Cut
Carat
Estimated around 3.0 to 5.0 carats based on visual size (for glass/imitation material)
Color
Light Yellow to Amber tint
Clarity
Heavily Included (contains numerous prominent gas bubbles and internal swirls typical of glass)
Shape
Oval Cabochon
Overall Assessment
The specimen is definitively identified as manufactured glass containing characteristic gas bubbles, completely lacking the gemological properties of a natural or lab-grown diamond.
Cut Quality
Fair to Poor (irregular cabochon polish and shape)
Brilliance
Low to Moderate, lacks the sharp light return and high refractive index of a genuine diamond
Fire
Minimal to none, completely lacks the spectral dispersion of diamond
Scintillation
Poor, lacks facet patterns required for dynamic sparkle
Proportions
Not applicable as this is a glass cabochon, lacks standard faceted proportions like table and depth percentages
Symmetry
Poor to Fair (asymmetrical oval shape)
Polish
Fair, shows some surface unevenness
Fluorescence
Indeterminate under visual light inspection
Inclusions
Abundant rounded gas bubbles of varying sizes throughout the volume, indicative of manufactured glass
Blemishes
Minor surface scratches and abrasions typical of softer imitation materials
Origin
Man-made glass imitation
Treatment Detection
None applicable as it is entirely glass and not a treated gemstone
Estimated Value
Nominal / Low value as a decorative glass item (less than $10)
Certification Estimate
Not eligible for certification by major gemological laboratories (GIA, AGS, IGI) as a diamond; would be identified as manufactured glass
Investment Potential
None; glass imitations hold no resale or investment value
Similar Diamonds
None, as this material is glass and shares no physical or optical properties with real diamonds
Setting Suggestions
Not recommended for fine jewelry settings due to low durability; simple bezel or wire-wrap costume settings if used decoratively
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaners, and hard impacts as glass is fragile and prone to scratching
Interesting Facts
The presence of rounded gas bubbles is a definitive diagnostic feature used by gemologists to instantly separate manufactured glass from natural and synthetic diamonds.
