Three-Stone, Marquise-Cut Lab Diamond, Six-Claw Platinum Setting
A considered composition of form and light, where the marquise silhouette meets the permanence of platinum.
This ring features a 1.50-carat marquise-cut laboratory-grown diamond, D colour and VVS1 clarity, held in a six-claw platinum setting that secures 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 distinctive silhouette that visually lengthens the finger. 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 introducing a quiet geometric contrast to the marquise’s brilliant faceting.
The 2mm band is crafted in 950 platinum — dense, naturally white, and resistant to wear. Its polished finish provides a cool, neutral foundation that lets the diamonds carry the light without warmth from the metal competing. The setting geometry is precise: six claws distribute hold evenly across the marquise’s perimeter, minimising metal coverage over the stone while maintaining structural integrity.
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 and finished with the highest standard of precision.

Care
950 platinum is exceptionally dense and naturally hypoallergenic, making it well suited for daily wear. Over time, the surface develops a soft patina — a characteristic that can be retained for a lived-in finish or polished to restore its original lustre.
