Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a delicate, tapered glow that seems to stretch the hand with quiet elegance. This semi-set halo ring in 18K rose gold frames a 9 x 4.5 mm marquise center stone with a gentle circle of pavé, enhancing its slender shape while offering a soft blush warmth from the band.

Crafted in Williamsburg, the rose gold band is polished to a satin finish that feels smooth against the skin, designed with a low-profile setting to sit comfortably beneath gloves or alongside stackable bands. The halo setting is meticulously hand-set to maximize light reflection, ensuring the marquise’s signature brilliance is both radiant and refined.

Each diamond is lab-grown, chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromise on sparkle or character.

This ring suits those who appreciate romantic geometry with a modern twist—its elongated form flatters slender fingers and pairs effortlessly with everyday wear. The semi-set design invites you to select a center stone that speaks to your personal story.
