The image shows a substance that is not a diamond. It appears to be a curved piece of iridescent plastic, resin, or synthetic material with rough, uneven edges and internal crazing.
The image shows a substance that is not a diamond. It appears to be a curved piece of iridescent plastic, resin, or synthetic material with rough, uneven edges and internal crazing. · Irregular/Curved (appears to be a broken or molded curved fragment, not a traditional diamond cut)
Uncut/Poor (the piece lacks faceted architecture or symmetry) Cut

Carat
Cannot provide a carat weight estimate for non-gemstone materials
Color
Colorless with intense iridescent sheen (not a standard diamond color grade)
Clarity
I3 / Heavily Included (contains significant internal fractures, crazing, and structural flaws)
Shape
Irregular/Curved (appears to be a broken or molded curved fragment, not a traditional diamond cut)
Overall Assessment
The specimen is not a diamond. It is an irregular, curved piece of translucent material, likely a polymer or resin, characterized by heavy internal fracturing and surface iridescence.
Cut Quality
Uncut/Poor (the piece lacks faceted architecture or symmetry)
Brilliance
Poor (material lacks the refractive index of a diamond)
Fire
High iridescent play-of-color due to structural interference, rather than diamond fire
Scintillation
Low to None
Proportions
N/A (does not conform to gemstone proportion standards)
Symmetry
Very Poor (the shape is asymmetrical and irregular)
Polish
Poor (the surface is pitted and rough)
Fluorescence
None observable, though it shows surface iridescence
Inclusions
Dense internal fractures, layered texture, and sheet-like internal crazing
Blemishes
Heavy surface scratching, jagged edges, and uneven texture
Origin
Synthetic industrial material or plastic/resin byproduct
Treatment Detection
N/A (material is non-diamond)
Estimated Value
Minimal to zero market value as a gemstone
Certification Estimate
N/A (standard grading labs like GIA or IGI would not grade this as a diamond)
Investment Potential
None
Similar Diamonds
None (this is not a mineral or gemstone)
Setting Suggestions
Not suitable for fine jewelry setting
Care & Maintenance
Avoid high heat or chemicals which may melt or dissolve synthetic materials
Interesting Facts
The iridescent effect on the surface suggests thin-film interference, common in aged plastics or certain iridescent coatings
