A few months in the making, this personal passion project was inspired by a vintage Cartier bracelet from my private collection (pictured in the last image). The original Cartier version is set with pyramidal cabochon-cut black onyx. I wanted to create a version using pyramid-shaped natural diamonds while honoring the craftsmanship of the original design.

Bespoke by Platt details:
Composed of 18k yellow gold and set with 10 carats of perfectly matched vintage princess-cut diamonds. The diamonds are inverted-set to achieve the pyramid shape we envisioned.
Weighing 16.40 Grams. 6.75 inches in length (can be shortened).
