Not a diamond; this specimen exhibits rounded gas bubbles and irregular internal structures characteristic of glass or synthetic simulant materials.
Not a diamond; this specimen exhibits rounded gas bubbles and irregular internal structures characteristic of glass or synthetic simulant materials. · Irregular freeform or cabochon-like bead
Poor (not faceted for optical performance, typical of novelty glass or slag). Cut
Carat
Estimated equivalent to roughly 3.0 to 4.0 carats by volume, though weight is irrelevant for glass.
Color
Colorless with warm brownish-yellow reflections due to lighting.
Clarity
Included heavily with spherical gas bubbles (I3 equivalent if graded as a gemstone).
Shape
Irregular freeform or cabochon-like bead
Overall Assessment
This object is definitively not a diamond. Gemological inspection reveals rounded internal gas bubbles and flow lines, confirming it is manufactured glass or a commercial simulant.
Cut Quality
Poor (not faceted for optical performance, typical of novelty glass or slag).
Brilliance
Low brilliance due to non-crystalline structure and gas inclusions.
Fire
Minimal dispersion, mostly localized prismatic color play from surface refraction.
Scintillation
Poor sparkle pattern, reflecting light uniformly rather than flashing facets.
Proportions
Non-standard, elongated rounded drop shape.
Symmetry
Poor, highly irregular.
Polish
Fairly smooth surface polish with visible internal striae.
Fluorescence
Not tested, likely inert.
Inclusions
Abundant rounded gas bubbles clearly visible throughout the interior.
Blemishes
Minor surface abrasions and contact marks.
Origin
Man-made glass / synthetic simulant.
Treatment Detection
N/A for natural diamonds; material is fundamentally manufactured glass.
Estimated Value
Nominal decorative value (under $10 USD).
Certification Estimate
Cannot be certified as a diamond; would be identified as glass or synthetic simulant by GIA or IGI.
Investment Potential
None; glass holds no gemological investment value.
Similar Diamonds
None, as this is glass and not a diamond.
Setting Suggestions
Not recommended for fine jewelry settings due to low durability.
Care & Maintenance
Standard gentle cleaning with mild soap and water; avoid hard impacts as glass is prone to chipping.
Interesting Facts
The presence of spherical gas bubbles is a classic diagnostic indicator separating manufactured glass from natural gemstones and diamonds.
