Not a diamond; this object appears to be a glass marble containing trapped air bubbles and internal color inclusions, resembling a toy or decorative glass piece rather than a crystalline diamond.
Not a diamond; this object appears to be a glass marble containing trapped air bubbles and internal color inclusions, resembling a toy or decorative glass piece rather than a crystalline diamond. · Round / Spherical
Poor / Commercial (smooth polished spherical bead, not a faceted gemstone cut) Cut
Carat
Not applicable (glass object; standard carat measurements apply to gemstones)
Color
Fancy Red internal core with clear outer glass casing
Clarity
Included (contains numerous round gas bubbles and structural flow lines)
Shape
Round / Spherical
Overall Assessment
This object is clearly not a diamond, but rather a manufactured glass marble. Its rounded shape, internal spherical gas bubbles, and visible red core confirm it is a decorative toy or glass specimen lacking any gemological value.
Cut Quality
Poor / Commercial (smooth polished spherical bead, not a faceted gemstone cut)
Brilliance
Low to moderate vitreous luster, lacking the high refractive index and dispersion of a diamond
Fire
Minimal to none; lacks the strong spectral dispersion characteristic of diamonds or high-index simulants
Scintillation
Poor sparkle and play of light due to non-faceted curved spherical surface and internal bubbles
Proportions
Spherical geometry with no traditional table, depth percentage, crown, or pavilion angles
Symmetry
Fair (roughly spherical but handmade or mass-produced shape may show slight deviations)
Polish
Good (smooth, glassy surface polish typical of manufactured glass)
Fluorescence
Unknown without UV testing
Inclusions
Numerous spherical gas bubbles (cavities) and swirl patterns typical of manufactured glass production
Blemishes
Minor surface scratches and abrasion marks typical of handled glass items
Origin
Man-made glass factory production
Treatment Detection
N/A (manufactured glass incorporating colored glass inserts and air bubbles)
Estimated Value
Nominal value (decorative glass object / toy marble, typically valued under a few dollars)
Certification Estimate
Not certifiable as a gemstone; gemological laboratories (GIA, IGI) do not grade glass toys or marbles
Investment Potential
None as an investment asset; purely decorative or nostalgic value
Similar Diamonds
None; this specimen shares no optical or physical properties with diamonds
Setting Suggestions
Not suitable for fine jewelry mountings; better suited for wire-wrapping, crafts, or display collections
Care & Maintenance
Clean with mild soap and warm water; avoid hard drops as glass is susceptible to chipping and cracking
Interesting Facts
The visible internal bubbles and bright red core are classic manufacturing traits of vintage or decorative glass marbles.
