INSIGNIA NOBLE, MARQUISE-CUT LAB DIAMOND, YELLOW GOLD

Three-Stone, Marquise-Cut Lab Diamond, Six-Claw Setting

A deliberate pairing of marquise geometry and warm gold, designed to command attention through proportion rather than volume.

This ring features a 1.50-carat marquise-cut laboratory-grown diamond, D colour and VVS1 clarity, set in six claws of 18-karat yellow gold that secure the stone at each pointed tip and along its curved flanks. The marquise cut — elongated, symmetrical, with a 2:1 length-to-width ratio at approximately 12×6mm — creates a silhouette that visually lengthens the finger and carries light across its full surface. Flanking the centre stone, two tapered baguette-cut diamonds (0.35ct each, D colour, VS2 clarity) sit flush against the shoulders, their step-cut facets providing a controlled, linear counterpoint to the marquise's brilliant faceting.

The 2.1mm band in 18-karat yellow gold is polished and precisely proportioned — wide enough to feel substantial on the hand, slim enough to let the three-stone composition remain the focal point. The warm tone of the gold interacts with the D-colour diamonds in a way that is distinct from platinum: the stones read brighter against the warmth, creating a deliberate contrast between the cool brilliance of the diamonds and the richness of the metal.

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

Part of the Insignia 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.
