Promise Square Emerald Cut Diamond Engagement Rin

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

Exquisitely balanced tapered baguette side stones set the stage for a striking centre diamond in the Promise setting — a timeless design rendered in sculptural white gold. At its heart, a certified 2.07 carat square emerald-cut diamond reveals the refined geometry and mesmerizing depth of its linear facets.

Renowned for its architectural clarity, the square emerald cut demands only the finest stones — those with exceptional quality and flawless transparency. That is why each diamond in our engagement collection is personally selected by a member of the Fuster family, ensuring impeccable provenance and radiant integrity.

With a total weight of 2.68 carats, this elegant composition is a celebration of clean lines, enduring craftsmanship, and quiet grandeur.

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.
