Not a diamond; appears to be colored glass or slag glass, or potentially a low-value green mineral/gemstone raw specimen.
Not a diamond; appears to be colored glass or slag glass, or potentially a low-value green mineral/gemstone raw specimen. · Rough, unpolished, irregular raw crystal form with melted or tumbled edges.
Not applicable (Uncut, raw specimen with no standard faceting). Cut
Carat
Estimated around 3.5 to 5.0 carats based on visual scale against fingers.
Color
Vivid bluish-green (Fancy Intense Greenish Blue color description).
Clarity
Included (Contains visible bubbles, swirls, and internal cloudiness typical of glass or heavily included minerals).
Shape
Rough, unpolished, irregular raw crystal form with melted or tumbled edges.
Overall Assessment
The specimen shown in the image is not a diamond or a precious gemstone. Visual indicators such as rounded surface features and internal bubbles strongly point toward colored glass or decorative slag. Professional gemological testing (such as a thermal conductivity probe or refractive index reading) would instantly verify it as non-diamond material.
Cut Quality
Not applicable (Uncut, raw specimen with no standard faceting).
Brilliance
Low to moderate, lacking the high refractive index and dispersion of a diamond.
Fire
Minimal to none; lacks the spectral dispersion characteristic of a fine gemstone.
Scintillation
Poor, due to lack of precision faceting and internal composition.
Proportions
Non-standard; raw, asymmetrical piece with no traditional crown, pavilion, or table proportions.
Symmetry
Poor / Irregular (Natural or manufactured raw asymmetry).
Polish
Raw/Unpolished with natural or tumbled texture, featuring conchoidal fractures typical of glass.
Fluorescence
Cannot be definitively determined without UV testing, though likely inert or moderate.
Inclusions
Gas bubbles and internal flow lines visible, strongly indicating synthetic/glass origin rather than a natural crystalline diamond or emerald.
Blemishes
Surface pitting, abrasion marks, and uneven texture.
Origin
Man-made glass or decorative slag; non-gemological natural origin.
Treatment Detection
Visual indicators suggest melted glass composition rather than a treated natural gemstone.
Estimated Value
Nominal value (under $10 USD) as a decorative or specimen piece of colored glass.
Certification Estimate
Would not be accepted by major grading labs (GIA, AGS, IGI) for diamond certification as it is not diamond material.
Investment Potential
None; holds no monetary or investment value as a gemstone.
Similar Diamonds
None, as this object is chemically and structurally distinct from a diamond.
Setting Suggestions
Wire-wrapped in sterling silver or copper for artisan jewelry, if desired.
Care & Maintenance
Standard gentle cleaning with mild soap and warm water; avoid harsh chemicals and impact.
Interesting Facts
Brightly colored green-blue glass is frequently mistaken for rough emerald, tourmaline, or colored diamonds by untrained observers.
