Promise Round Diamond Engagement Ring

Please contact us directly should you require a ring in a size that is not shown on the website.

The Promise setting in white gold is a timeless interpretation of the classic three-stone engagement ring — an ode to enduring love, brought to life through the poetic craftsmanship of Fuster. Two finely cut pear-shaped side stones gently frame the brilliance of a 1.52 carat certified round brilliant-cut diamond, naturally drawing the eye to its fire and clarity while amplifying its radiance.

With a total weight of 1.85 carats, this design is as elegant as it is intentional — a harmony of form and emotion.

Each diamond in our engagement collection is meticulously shaped by Fuster’s master artisans to reveal its individual character, while every bespoke setting is handcrafted to cradle the unique silhouette of your chosen stone.

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.
