Not a diamond; this is Labradorite, a feldspar mineral exhibiting labradorescence. - Irregular tumbled cushion shape

Carat

Not applicable as this is a gemstone mineral, not a faceted diamond.

Color

Not applicable; exhibits grey body color with multicolored iridescence (labradorescence).

Clarity

Included, displaying internal fractures, twinning planes, and mineral inclusions typical of feldspar.

Shape

Irregular tumbled cushion shape

Overall Assessment

This is a natural specimen of labradorite displaying characteristic labradorescence and twinning lines, completely distinct from any diamond.

Cut Quality

Not applicable; tumbled and polished cabochon-style stone, not a diamond cut.

Brilliance

Limited brilliance; features schiller effect (labradorescence) rather than standard diamond brilliance.

Fire

Displays spectral flashes of color (blue, green, yellow, orange) known as labradorescence, not traditional fire.

Scintillation

Dynamic play-of-color shifting across the surface as the angle of light changes.

Proportions

N/A for cabochon stones

Symmetry

Asymmetrical tumbled stone

Polish

Good overall polish with natural surface pitting and grain lines visible

Fluorescence

Not applicable

Inclusions

Strong polysynthetic twinning planes, natural fractures, and dark mineral inclusions.

Blemishes

Surface scratches, pitting, and natural cleavage lines.

Origin

Commonly found in Canada (Labrador), Madagascar, Finland, and Australia.

Treatment Detection

No treatments detected; natural untreated feldspar.

Estimated Value

Low commercial value ($10 to $50 depending on size and quality of the flash).

Certification Estimate

Not certified by standard diamond grading labs (GIA, AGS). Colored stone reports may be issued by institutions like GIA or GRS.

Investment Potential

None; considered a decorative and ornamental mineral rather than an investment-grade gemstone.

Similar Diamonds

None, as this is a feldspar mineral and not a diamond or diamond simulants.

Setting Suggestions

Best set in artisan bezel settings using sterling silver or yellow gold to complement the earthy tones.

Care & Maintenance

Avoid harsh chemicals, ultrasonic cleaners, and sudden temperature changes due to distinct cleavage planes.

Interesting Facts

Labradorite is famous for its optical phenomenon called labradorescence, caused by light diffraction in lamellar intergrowths.
