Not a diamond; this appears to be an optical glass prism or coated quartz crystal displaying internal reflections and thin-film interference colors. - Irregular multifaceted block / prism

Carat

Not applicable (mineral specimen/glass object, measured in grams rather than carats)

Color

Fancy multicolored (due to coating and internal light refraction)

Clarity

Not applicable to gem-grade diamonds

Shape

Irregular multifaceted block / prism

Overall Assessment

An interesting optical prism or coated quartz crystal rather than a diamond, notable for its striking rainbow interference colors and internal reflections.

Cut Quality

Not applicable

Brilliance

High internal reflection and spectral dispersion

Fire

Extremely high spectral dispersion due to prism effect and possible coating

Scintillation

Dynamic play of light driven by movement against light sources

Proportions

Not applicable to standard diamond cut standards

Symmetry

Asymmetrical / handmade optical geometry

Polish

Smooth optical polish on visible facets

Fluorescence

Not applicable

Inclusions

Internal fracture planes and trapped air bubbles typical of glass or untreated natural quartz

Blemishes

Surface chips and abrasion near edges

Origin

Man-made optical glass or treated quartz

Treatment Detection

Surface coating visible via rainbow thin-film interference patterns

Estimated Value

Nominal decorative or educational value

Certification Estimate

Not gradable by standard diamond laboratories (GIA, AGS, IGI)

Investment Potential

None; ornamental or novelty value only

Similar Diamonds

None, as this is fundamentally not a diamond

Setting Suggestions

Not recommended for jewelry due to material softness and fragility

Care & Maintenance

Handle with care to avoid chipping; clean with mild soap and water, avoid harsh chemicals

Interesting Facts

Demonstrates spectacular optical physics phenomena including refraction, reflection, and thin-film interference
