Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, radiant beam across the hand. This semi-set engagement ring invites you to select a 9 x 4.5 mm marquise stone, whose tapered points and graceful curves evoke a sense of refined drama and vintage allure.

Crafted from warm 14K yellow gold, the band is shaped with subtle artisan touches—smoothly contoured for comfort and designed to sit low against the finger. The accent settings frame the center stone with delicate precision, enhancing its light play without overpowering its distinctive shape. Each ring is finished by hand in our Williamsburg studio, inspected for balance and polish that endures daily wear.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

The low-profile setting and slender band make this ring ideal for those who appreciate a piece that feels as natural as it looks striking—equally suited for stacking or solo wear. Its dimensions flatter longer fingers, while the secure mounting ensures everyday confidence.

Should you wish to adjust sizing or explore custom accents, our Brooklyn studio offers personalized consultations with no pressure and transparent timelines.
