Not a diamond; this appears to be a piece of rough or cut colored glass or synthetic material, dyed or strongly lit with blue light, rather than carbon-based diamond.
Not a diamond; this appears to be a piece of rough or cut colored glass or synthetic material, dyed or strongly lit with blue light, rather than carbon-based diamond. · Irregular raw slab or fragment, non-standard shape
Poor / Uncut rough fragment Cut
Carat
Cannot be precisely determined from visual assessment alone, but roughly estimated at over 10 carats based on visible bulk.
Color
Deep Fancy Vivid Blue (though likely artificial coloring or lighting effect)
Clarity
Included / Imperfect with numerous internal fractures and bubbles typical of glass
Shape
Irregular raw slab or fragment, non-standard shape
Overall Assessment
This item is conclusively not a diamond. Gemological evaluation indicates it is a piece of blue-tinted glass or synthetic simulant showing characteristic conchoidal fracture patterns.
Cut Quality
Poor / Uncut rough fragment
Brilliance
Low due to lack of proper diamond faceting and optical properties
Fire
Minimal to none, lacks the high dispersion index of diamond
Scintillation
Poor due to lack of facet interaction
Proportions
Non-standard, irregular slab proportions
Symmetry
Poor / Asymmetrical
Polish
Rough unpolished surface with visible conchoidal fractures
Fluorescence
Unknown without UV testing, though strong artificial glow is present
Inclusions
Large internal fractures, gas bubbles, and structural irregularities common in glass
Blemishes
Surface scratches, pits, and crude chipping
Origin
Synthetic / Man-made glass material
Treatment Detection
Colored glass simulants often utilize artificial colorants or surface coatings
Estimated Value
Nominal decorative or craft value, negligible gemological value
Certification Estimate
Uncertifiable as a diamond by major labs like GIA or IGI
Investment Potential
None as an investment asset
Similar Diamonds
None, as this is a glass simulant rather than a diamond
Setting Suggestions
Wire-wrapped or bezel settings for artisan jewelry pieces
Care & Maintenance
Avoid harsh impacts, chemicals, and extreme temperature changes to prevent shattering
Interesting Facts
Brightly colored blue glass is frequently used as an affordable simulant for sapphires and blue diamonds in costume jewelry.
