CLARITAS CATHÉDRALE, RADIANT-CUT LAB DIAMOND

Cathedral, Radiant-Cut Lab Diamond, Four-Claw Hidden Halo with ¾ Round Pavé Setting

Five carats of radiant-cut lab diamond in a cathedral setting — the most commanding stone in the Claritas collection.

This ring features a 5.00-carat radiant-cut laboratory-grown diamond, D colour and VVS1 clarity, held in four claws above a cathedral setting with a 1.44:1 length-to-width ratio. The radiant cut — the only brilliant-cut shape with trimmed corners — combines the elongated profile of an emerald cut with the full fire and brilliance of a round brilliant's faceting pattern. At five carats, the stone's presence is substantial: approximately 12×9mm of diamond face, with exceptional light performance across the full table.

The cathedral setting — where the band arches upward on each side to meet the base of the stone — elevates the diamond above the finger and creates a distinctive profile silhouette. Beneath the centre stone, a hidden halo of micro-set round diamonds encircles the base. The band carries ¾ round pavé diamonds — micro-set stones running three-quarters of the shank's circumference, producing controlled brilliance that complements without competing with the stone above. The 3mm band provides structural mass appropriate for a ring of this scale.

Optically, chemically, and physically identical to mined diamonds, every stone is selected for its exceptional colour and clarity — not as an alternative, but as a deliberate choice.

Part of the Claritas Collection — Heritage & Co.'s lab diamond line, where every stone is selected for exceptional colour and clarity. Each piece is crafted to order in 18-karat yellow gold and finished with the highest standard of precision.
