Lab-Grown Diamond Engagement Ring

Imagine the moment sunlight catches the elongated facets of a marquise diamond, casting a delicate, tapered glow across your hand. This semi-set halo engagement ring foundation in 18K yellow gold invites you to select a center stone up to 12 by 6 millimeters, framing it with a handcrafted halo that amplifies brilliance while maintaining a refined silhouette.

Each band is meticulously shaped and polished in our Williamsburg studio, the warm gold surface smooth to the touch with a subtle comfort fit that rests effortlessly for daily wear. The low-profile setting balances presence with practicality, designed to slip easily beneath gloves or stack alongside complementary bands without catching.

Our commitment to lab-grown diamonds ensures clarity and sparkle with a significantly reduced environmental footprint, reflecting a modern approach to ethical jewelry.

This ring suits those who appreciate architectural elegance and a statement that elongates the finger, perfect for hands seeking a blend of vintage-inspired drama and contemporary craftsmanship.

Should you wish to adjust the band size, our in-house artisans provide expert resizing to maintain the ring’s integrity and comfort.
