Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc, lending a subtle drama to the hand. This semi-set halo mounting in 18K white gold frames a 7 x 3.5 mm marquise center stone with a delicate ring of pavé, designed to amplify brilliance while maintaining a low profile.

Crafted in Williamsburg, this setting balances technical precision with everyday comfort: the band’s smooth interior ensures a comfort fit, while the halo’s modest height keeps it glove-friendly and stackable. Each curve and prong is hand-finished and inspected to secure your stone with quiet confidence.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and sparkle with a reduced environmental footprint.

Ideal for those who appreciate architectural elegance paired with practical wearability, this halo setting complements the marquise’s tapered points and elongates the finger without overwhelming it.

Should you need resizing or prefer a different center stone, our studio offers personalized consultations to tailor your ring precisely.
