Designed to illuminate the natural brilliance of its centre stone, the Promise engagement ring in white gold features a captivating 1.22 carat certified oval-cut diamond, flanked by a pair of perfectly matched pear-shaped side stones. This delicate, symmetrical arrangement draws the eye inward — a graceful composition that highlights both the fire and form of the central diamond.

With a total weight of 1.88 carats, this setting offers a refined expression of timeless elegance.

Each diamond in our bridal collection is personally selected by a member of the Fuster family, ensuring not only exceptional quality but also perfect provenance. Every bespoke setting is handcrafted by our master artisans to cradle the unique silhouette of your chosen Fuster diamond with precision and reverence.

Each Fuster creation is unique. As a result, size, carat weight and stone qualities can vary slightly from one to another. For detailed information, please contact us or book an in-store appointment.
