Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set halo ring invites your choice of a 6 x 3 mm center stone, framed by a delicate halo that amplifies its signature brilliance.

Crafted from warm 10K yellow gold, the band is shaped with subtle contours for a comfortable fit that feels effortless from morning coffee to evening strolls in Williamsburg. The artisan’s touch is evident in the precise prong setting and the smooth polish, ensuring the halo sits low enough for daily wear without catching.

Each lab-grown diamond offers clarity and sparkle with a smaller environmental footprint, reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

Designed for those who appreciate refined elegance with a modern edge, this ring complements slender fingers and pairs beautifully with stackable bands or a simple wedding band. Its low-profile setting makes it glove-friendly and practical for everyday life.
