High internal light reflection with some localized extinction (dark areas).
Fire
Moderate spectral color dispersion visible in the crown facets.
Scintillation
Crisp, blocky sparkle pattern characteristic of a modified brilliant radiant cut.

Good
Polish

None to Faint
Inclusions
Visible dark crystals near the center table and internal feathering towards the bottom corner.
Blemishes
Minor surface scratches and slight nicking on the girdle edge.
Origin
Likely mined origin (African or Canadian characteristics).

Estimated Value
$35,000 - $55,000 USD depending on final certification.
Certification Estimate
GIA (Gemological Institute of America) would likely grade this H/SI2.

Similar Diamonds
Crushed ice radiant cuts of comparable dimensions.
Setting Suggestions
Four-prong platinum setting or a halo design to enhance the size and protect the corners.
Care & Maintenance
Regular professional cleaning; avoid ultrasonic cleaners if feathers are deep near the surface.
