Not a diamond; this is a piece of green glass or slag, displaying conchoidal fracture typical of amorphous materials rather than crystalline diamond structure.
Not a diamond; this is a piece of green glass or slag, displaying conchoidal fracture typical of amorphous materials rather than crystalline diamond structure. · Raw, unpolished, irregularly fractured fragment (rough/slag)
Not applicable (uncut raw fragment with conchoidal fractures) Cut
Carat
Not applicable for a non-gemstone specimen, though visually substantial in mass as a piece of glass.
Color
Vivid intense green
Clarity
Included / Heavily flawed due to internal bubbles, flow lines, and fractures inherent in glass.
Shape
Raw, unpolished, irregularly fractured fragment (rough/slag)
Overall Assessment
The specimen shown in the image is a green glass or slag fragment, easily identified by its conchoidal fractures, internal bubbles, and lack of true crystal faces. It holds no gemological or diamond value.
Cut Quality
Not applicable (uncut raw fragment with conchoidal fractures)
Brilliance
Vitreous luster, limited brilliance compared to crystalline gemstones
Fire
Low dispersion, characteristic of glass rather than diamond or high-dispersion gems
Scintillation
Minimal, reflecting light off internal fracture planes rather than precise facets
Proportions
Not applicable (irregular rough chunk)
Symmetry
Asymmetrical due to random fracture patterns
Polish
Raw fractured surfaces, unpolished
Fluorescence
Unknown without UV testing, though common green glass may show weak to moderate fluorescence depending on additives.
Inclusions
Internal gas bubbles and flow lines typical of manufactured glass
Blemishes
Surface chips, conchoidal rippling, and rough edges
Origin
Man-made industrial or decorative glass
Treatment Detection
Dyed or colored in mass during glass production
Estimated Value
Nominal decorative or collector value (low monetary value, typically sold as decorative cullet or slag glass).
Certification Estimate
None; major grading labs like GIA or IGI do not certify decorative glass or slag.
Investment Potential
No investment value; decorative or novelty item only
Similar Diamonds
None, as this is completely unrelated to diamond
Setting Suggestions
Not suitable for fine jewelry setting due to low hardness and fragile nature
Care & Maintenance
Handle with care to avoid chipping the sharp edges; clean with mild soapy water.
Interesting Facts
Many people mistake vividly colored slag glass found outdoors for rough gemstones like emerald, peridot, or colored diamond due to its bright coloration.
