Lab-Grown Diamond Engagement Ring

Light catches the marquise’s tapered points, casting a subtle, elongated sparkle that draws the eye along the finger’s natural line. This solitaire semi-set invites your choice of a 6 x 3.5 mm lab-grown diamond, ready to become the centerpiece of a refined engagement ring.

Crafted from 18K white gold, the mounting features a low-profile setting designed for everyday wear. Its sleek silhouette minimizes snagging while the secure prongs hold your stone with quiet confidence. The band’s smooth finish and balanced weight ensure a comfortable fit that feels as natural as it looks.

Each ring is handmade in our Williamsburg studio, where precision meets thoughtful design. The ethical clarity of lab-grown diamonds complements the sustainable ethos behind every piece, offering a responsible alternative without compromise.

Ideal for those who appreciate modern geometry and subtle elegance, this setting suits a slender finger or pairs seamlessly with stackable bands. Its modest height makes it glove-friendly and unobtrusive for daily life.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to tailor your ring with care and expertise.
