Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc of rose gold. This semi-set three-stone engagement ring invites your choice of a 9 x 4.5 mm center stone, poised to reflect light with a graceful, almost lyrical brilliance.

Crafted in warm 14K rose gold, the band’s gentle curve and polished finish offer a subtle glow against the skin. The three-stone setting balances presence with wearability, designed with a low profile that slips comfortably beneath gloves or sleeves. Each prong is hand-finished in our Williamsburg studio, ensuring the mounting cradles your diamond securely while maintaining an elegant silhouette.

Our lab-grown diamonds provide clarity and sparkle without compromise, reflecting a commitment to ethical jewelry that respects both people and planet.

This ring suits those who appreciate romantic geometry with a modern edge—its slender shape elongates the finger, while the three-stone arrangement adds narrative depth. The comfort fit band supports daily wear, whether worn solo or stacked with complementary bands.

Should you need resizing, our Brooklyn studio offers attentive adjustments to ensure a perfect fit without disrupting the ring’s refined lines.
