Not a diamond; appears to be a piece of broken glass or quartz crystal
Not a diamond; appears to be a piece of broken glass or quartz crystal · Irregular raw fragment / amorphous shard
Not applicable (uncut or fractured shard) Cut

Carat
Cannot be accurately determined visually from an uncalibrated photograph, estimated roughly between 5 to 10 carats equivalent weight based on volume
Color
Colorless / transparent with surface reflections
Clarity
Not applicable (contains internal fractures, bubbles, or irregularities typical of glass)
Shape
Irregular raw fragment / amorphous shard
Overall Assessment
Visual inspection indicates this specimen is a clear shard of glass or quartz rather than a rough diamond. It lacks the characteristic octahedral crystal habit, high refractive index, and adamantine luster of diamond.
Cut Quality
Not applicable (uncut or fractured shard)
Brilliance
Low to moderate vitreous luster, typical of glass rather than diamond
Fire
Minimal dispersion / fire, far lower than a genuine diamond
Scintillation
Poor light return and sparkle due to lack of standard facet proportions
Proportions
Not applicable
Symmetry
Asymmetrical / irregular
Polish
Raw / unpolished fracture surfaces
Fluorescence
Unknown without UV testing
Inclusions
Possible internal stress fractures or air bubbles common in manufactured glass
Blemishes
Chipped edges, surface abrasions, and irregular fracture planes
Origin
Man-made glass fragment
Treatment Detection
None applicable
Estimated Value
Minimal to zero commercial or gemological value (novelty or decorative glass shard)
Certification Estimate
Will not be certified by major gemological laboratories (GIA, AGS, IGI) as a diamond
Investment Potential
None
Similar Diamonds
None
Setting Suggestions
Not suitable for fine jewelry settings due to fragile nature and lack of gemstone status
Care & Maintenance
Handle with care to avoid cuts from sharp edges if glass
Interesting Facts
Many non-gem materials such as quartz, clear glass, and white topaz are frequently mistaken for rough diamonds by amateurs
