Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light like a shard of morning sun. This three-stone semi-set engagement ring frames an 8 x 4 mm marquise center with two delicate side stones, each carefully positioned to enhance the stone’s tapered elegance.

Handcrafted in 18K white gold, the mounting features a low-profile setting that nestles close to the finger, balancing presence with everyday comfort. The band’s smooth finish and precise prong work reflect hours of artisan attention, ensuring durability without sacrificing refined detail.

Each diamond is lab-grown, offering a clarity and brilliance that honors both the environment and your values. This ethical choice complements the studio’s commitment to sustainable fine jewelry made in Williamsburg, Brooklyn.

Designed for those who appreciate architectural grace and subtle sparkle, the marquise shape elongates the hand, while the three-stone layout adds narrative depth—ideal for stacking or wearing solo with ease. Its comfort fit and modest profile make it glove-friendly and suited for daily wear.

Should you need resizing or prefer a custom stone, the semi-set design allows flexible personalization without delay.
