Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This three-stone semi-set engagement ring frames a 10 x 5 mm marquise center with two delicately positioned side stones, each held in a refined 18K white gold setting that balances strength with subtlety.

Crafted in our Williamsburg studio, the band is shaped for comfort with a smooth, low-profile shank that sits close to the finger, ideal for everyday wear. The prongs are meticulously hand-finished to secure the stones while allowing maximum light to pass through, enhancing the marquise’s signature brilliance and tapering elegance.

Each diamond is lab-grown, offering a clarity and sparkle indistinguishable from mined stones, with a conscious approach to sustainability and ethical sourcing that quietly underpins the design.

The elongated marquise shape naturally elongates the finger, making this ring a graceful choice for those who appreciate architectural lines paired with classic symbolism. Its three-stone layout invites stacking or pairing with a wedding band without overwhelming the hand.

Should you need resizing, our in-house artisans ensure a precise fit without compromising the ring’s integrity or finish. Typical lead times reflect our commitment to handcrafted quality.
