Not a diamond; appears to be quartz, glass, or an alternative mineral with conchoidal fracture and iridescent play of color.
Not a diamond; appears to be quartz, glass, or an alternative mineral with conchoidal fracture and iridescent play of color. · Rough / Ungraded, organic or raw irregular crystalline mass.
Not applicable; raw unstructured material with conchoidal breakage. Cut
Carat
Not applicable for a cut gemstone; large raw specimen visually exceeding 10 carats.
Color
Colorless with iridescent interference effects.
Clarity
Not applicable; contains internal fractures, structural striae, and inclusions.
Shape
Rough / Ungraded, organic or raw irregular crystalline mass.
Overall Assessment
This specimen is a raw, irregular mineral or glass fragment showing conchoidal fracture patterns and iridescent surface effects. It is definitely not a diamond and lacks standard gemological cutting and grading characteristics.
Cut Quality
Not applicable; raw unstructured material with conchoidal breakage.
Brilliance
Low to moderate vitreous luster, limited to surface reflections.
Fire
Minimal dispersion, though thin-film interference creates localized rainbow hues.
Scintillation
Poor due to lack of facet geometry and symmetrical light return.
Proportions
Non-standard raw formation with no traditional table, crown, or pavilion.
Symmetry
Asymmetrical due to raw natural or fractured state.
Polish
Unpolished, raw fracture surfaces displaying conchoidal ripples.
Fluorescence
Indeterminate from visual assessment alone.
Inclusions
Heavy internal stress fractures, fissures, and optical distortions.
Blemishes
Surface chips, irregular conchoidal fractures, and natural weathering lines.
Origin
Natural mineral or synthetic glass rough specimen.
Treatment Detection
Possible surface coatings or heat fracturing evident from iridescence.
Estimated Value
Nominal decorative or mineral specimen value.
Certification Estimate
Not certifiable as a diamond by standard grading laboratories (GIA, AGS, IGI).
Investment Potential
None as an investment gemstone; strictly ornamental or collectible.
Similar Diamonds
None, as this specimen lacks diamond crystal structure and hardness.
Setting Suggestions
Wire-wrapped or bezel setting if used as a raw mineral specimen jewelry piece.
Care & Maintenance
Avoid harsh impacts to prevent further fracturing along cleavage or conchoidal planes; clean with mild soapy water.
Interesting Facts
The rainbow colors visible are caused by thin-film interference (light diffraction through microscopic surface cracks) rather than true diamond fire.
