Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette casting a subtle glow across the hand. This three-stone semi-set ring features a 7 x 5 mm oval center, poised to frame your chosen gem with delicate 18K white gold shoulders.

Each band is meticulously crafted in our Williamsburg studio, where the cool, smooth finish of 18K white gold is shaped and polished to a refined comfort fit. The low-profile setting balances presence with everyday ease, designed to slip effortlessly beneath gloves or stack alongside other bands.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint. This ring’s architecture highlights the oval’s graceful elongation, flattering a variety of hand shapes and lending a modern yet timeless geometry.

Whether worn solo or paired, the three-stone design invites personal meaning—each side stone a quiet companion to the center’s luminous heart. Resizing is available to ensure a seamless fit, crafted with care to maintain the ring’s sculptural integrity.
