Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances across the skin. This semi-set three-stone engagement ring invites you to select a center stone measuring 9 by 4.5 millimeters, its tapered shape lending a graceful drama to the hand.

Crafted from warm 18K yellow gold, the band is designed with a low-profile setting that balances presence with everyday comfort. Each prong and curve is meticulously finished in our Williamsburg studio, ensuring a seamless fit that complements stacking or solo wear. The three-stone arrangement offers subtle movement and layered light play, a quiet testament to artisan skill.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, chosen for their clarity and sustainable origins without compromise on brilliance.

Ideal for those who appreciate a ring that feels as natural as it looks—whether worn daily or layered with other bands. The slender marquise shape visually elongates the finger, while the comfort fit band sits flush beneath gloves or sleeves.
