Lab-Grown Diamond Engagement Ring

When light catches the elongated marquise center, its tapered points create a striking silhouette that subtly elongates the finger. This semi-set halo ring in 18K white gold offers a refined foundation, designed to cradle a 9 x 4.5 mm marquise diamond with precision and grace.

Crafted with a low-profile halo setting, the band balances presence with everyday comfort, ensuring it sits close to the hand without catching. The smooth 18K white gold shank is polished to a satin finish, enhancing wearability and durability for daily life in Williamsburg.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that deliver clarity and brilliance with a smaller environmental footprint. The semi-set design invites you to select a center stone that matches your vision, supported by expert guidance from our Brooklyn studio.

Ideal for those who appreciate architectural elegance paired with practical design, this ring suits slender to medium finger shapes and layers effortlessly with other bands. Its low profile makes it glove-friendly and unobtrusive for active lifestyles.

Should you need resizing or prefer a custom adjustment, our in-studio process ensures a precise fit without compromising the ring’s integrity. Typical lead times align with our careful handcrafting standards.
