Not a diamond; appears to be a raw mineral specimen, synthetic material, or colored glass illuminated by a strong blue light/laser, lacking true diamond characteristics.
Not a diamond; appears to be a raw mineral specimen, synthetic material, or colored glass illuminated by a strong blue light/laser, lacking true diamond characteristics. · Rough uncut bar / irregular elongated crystal fragment
Not applicable (rough uncut specimen) Cut
Carat
Cannot be accurately determined from visual assessment without precise dimensions and density testing; estimated roughly at 5-10 carats equivalent volume
Color
Deep Fancy Blue (under illumination)
Clarity
Included / heavily included with internal fractures and inclusions
Shape
Rough uncut bar / irregular elongated crystal fragment
Overall Assessment
The item in the image is not a diamond. It displays the characteristics of a rough, fracture-filled mineral bar or synthetic material strongly reacting to a blue light source, requiring professional laboratory testing for definitive identification.
Cut Quality
Not applicable (rough uncut specimen)
Brilliance
Low due to lack of standard facet alignment and high inclusion level
Fire
Minimal dispersion visible due to dominant blue luminescence and opaque inclusions
Scintillation
Poor sparkle pattern, reflects light diffusely rather than through crisp internal reflections
Proportions
Non-standard rough bar proportions, lacks faceted table, crown, and pavilion angles
Symmetry
Asymmetrical rough crystal form
Polish
Unpolished natural or fractured surface texture
Fluorescence
Very Strong Blue reaction under ultraviolet light or direct laser excitation
Inclusions
Visible internal feathers, fractures, and structural irregularities
Blemishes
Surface chips, natural growth marks, and uneven fractures
Origin
Undetermined; potentially synthetic or treated material given the intense localized blue fluorescence
Treatment Detection
Potential artificial coloring, coating, or dye evidenced by the intense unnatural blue glow under light
Estimated Value
Nominal value as a mineral specimen or educational piece, little to no commercial value as a gemstone
Certification Estimate
Not standard for gemological grading labs like GIA or AGS in this state; would likely require advanced spectroscopy to identify exact material composition
Investment Potential
None; this specimen holds no traditional gemstone investment value
Similar Diamonds
None, as this specimen shares no optical or physical properties with standard gem-grade diamonds
Setting Suggestions
Wire-wrapped rough pendant or custom bezel setting if intended for novelty jewelry
Care & Maintenance
Store separately in a soft pouch, avoid harsh chemicals and ultrasonic cleaning until material composition is confirmed
Interesting Facts
Strong fluorescence or luminescence under specific lighting conditions is common in certain minerals and synthetic substitutes, often used for demonstration purposes
