Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set platinum mounting is crafted with a low-profile design, ensuring the stone sits close to the hand for everyday comfort and secure wear.

Each band is meticulously finished in platinum, prized for its durability and subtle sheen, with precise prong settings engineered to cradle a 7 x 3.5 mm marquise center stone. The mounting’s streamlined form balances technical assurance with understated elegance, making it ideal for those seeking a ring that complements an active lifestyle without sacrificing refinement.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and sparkle with a reduced environmental footprint. The slender profile and smooth edges make this ring glove-friendly and stackable, perfect for layering alongside wedding bands or personal accents.

Should you need resizing, our in-studio experts in Williamsburg handle adjustments with care, preserving the integrity of the setting. Typical lead times accommodate custom fitting and final polishing, ensuring a seamless experience from design to delivery.
