A high-quality colorless rough diamond fragment showing good transparency but significant internal structural complexity.

Cut Quality

Not Applicable (Uncut)

Minimal (restricted to surface reflections)

Proportions

N/A - Irregular rough fragment

Similar Diamonds

Uncut octahedral or macle rough crystals

Setting Suggestions

Best suited for a bespoke 'Rough Diamond' organic setting or lapidary faceting

Care & Maintenance

Safe to clean with ultrasonic, but avoid sharp impacts on cleavage planes
