Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful, confident line. This semi-set halo engagement ring foundation in 14K yellow gold frames an 8 x 4 mm marquise center with a modern-minimal edge, designed to amplify the stone’s natural brilliance once chosen.

Crafted with precision in Williamsburg, the band’s smooth finish and subtle profile ensure daily comfort without sacrificing presence. The halo setting, ready to embrace your selected marquise, adds a structured glow that enhances light play while maintaining a sleek silhouette. Each piece undergoes meticulous hand inspection to meet exacting standards of finish and durability.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and sustainability without compromise. This ring’s low-profile setting and slender band make it ideal for those who appreciate refined geometry and a piece that layers effortlessly with other bands.

Designed for wearers who favor clean lines and confident form, this semi-set ring invites you to select a marquise stone that reflects your unique story. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn studio.
