Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the hand with quiet elegance. This semi-set halo engagement ring in 18K yellow gold frames a 7 x 3.5 mm marquise stone, inviting you to select the center that speaks most to your story.

Crafted in Williamsburg, the band’s warm gold glow complements the marquise’s vintage-inspired shape, while the halo setting enhances brilliance without overwhelming. The low-profile design ensures daily comfort, with a smooth finish that feels as natural as the moment you slip it on.

Each ring is thoughtfully made with lab-grown diamonds, reflecting a commitment to ethical jewelry that honors both beauty and sustainability.

Its slender band and modest height make this ring ideal for those who appreciate refined detail and a piece that layers effortlessly with other bands or stands alone with quiet confidence.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as personal as the promise it represents.
