Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set halo ring invites your choice of a 6 x 3 mm marquise center, cradled by a delicate circle of pavé stones that amplify its graceful silhouette.

Crafted in 18K white gold, the band is polished to a soft sheen, offering a cool, smooth touch that complements daily wear. The halo setting balances sparkle with subtlety, designed low enough to slip comfortably beneath gloves or stack alongside other bands without catching.

Each ring is finished in our Williamsburg studio, where expert hands inspect every facet and prong to ensure a refined, secure setting. The choice of a lab-grown diamond reflects a commitment to clarity and sustainability, marrying beauty with conscience.

Its slender profile suits hands that appreciate elegance with a hint of drama—elongating fingers and catching light with every movement. Whether paired with a simple wedding band or worn solo, this ring adapts effortlessly to your lifestyle.
