Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, graceful silhouette that seems to stretch beyond the finger. This semi-set halo engagement ring in 18K yellow gold frames a 7 x 3.5 mm marquise stone, its sharp geometry softened by a delicate halo that amplifies brilliance without excess.

Handcrafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable, everyday wear experience. The halo setting is meticulously aligned to enhance light reflection, while the 18K yellow gold offers a warm, enduring foundation polished to a subtle sheen.

Each lab-grown diamond is chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromise on sparkle or structure.

Designed for those who appreciate modern minimalism with architectural clarity, this ring sits close to the hand, making it ideal for stacking or pairing with a wedding band. Its slender marquise shape visually elongates the finger, lending an elegant confidence to daily life.

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