Carat
Estimated around 3.0 to 5.0 carats based on visual size relative to a finger.
Color
Vivid blue (Fancy Dark Blue or Cobalt Blue description).
Clarity
Included / Heavily flawed due to internal fractures, striations, and surface wear.
Shape
Irregular raw fragment / unstructured slab.
Overall Assessment
The specimen shown in the image is definitively not a diamond. It lacks the crystal structure, optical properties, and standard faceting of a diamond, presenting instead as a blue translucent raw slab or glass fragment with visible surface scratches and internal striations.
Cut Quality
Not applicable (uncut raw or broken fragment).
Brilliance
Low; limited light return due to rough surface texture and lack of facets.
Fire
Minimal dispersion observed.
Scintillation
Poor; lacks structured facet patterns to create dynamic sparkle.
Proportions
Non-standard; inconsistent thickness and irregular edges.
Symmetry
Poor / Asymmetrical due to irregular natural or fractured shape.
Polish
Poor / Unpolished rough surface with visible scratches and striations.
Fluorescence
Indeterminate from visual assessment alone.
Inclusions
Numerous internal fractures, feather inclusions, and linear striations.
Blemishes
Surface scratches, abrasions, and chipping along the edges.
Origin
Indeterminate; potentially man-made glass, synthetic spinel, or raw mineral fragment.
Treatment Detection
Visual signs of surface wear and possible molded or fractured manufacturing marks.
Estimated Value
Nominal / Low value as a decorative or specimen piece (less than $10 unless verified as a rare gemstone).
Certification Estimate
Not eligible for standard diamond grading laboratories (e.g., GIA, AGS); requires gemological testing (e.g., GIA Identification Report) to confirm material.
Investment Potential
None; this specimen holds no investment or resale value as a gemstone.
Similar Diamonds
None, as this object is not a diamond.
Setting Suggestions
Wire-wrapped setting or custom bezel if used as a raw mineral jewelry piece.
Care & Maintenance
Handle with care to prevent further chipping; clean with mild soapy water and a soft brush if mineral-based.
