Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This semi-set halo engagement ring invites you to choose a center stone that measures 14 by 7 millimeters, its tapered shape lending a graceful, almost poetic drama to the hand.

Crafted in warm 14K yellow gold, the band is designed with a halo setting that embraces the center stone, amplifying its brilliance while maintaining a refined profile. The low-set halo nestles close to the finger, offering comfort for daily wear without sacrificing sparkle. Each curve and prong is meticulously finished in our Williamsburg studio, ensuring a smooth feel and enduring strength.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, combining clarity and sustainability in a single choice. This ring suits those who appreciate a statement piece that remains elegant and wearable—its slender shape elongates the finger, while the halo adds a subtle glow that complements stacking or solo wear.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the ring’s balance and comfort. Typical lead times reflect our dedication to handcrafted quality, with every piece made to order in Brooklyn.
