Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc of rose gold. This semi-set halo engagement ring invites your choice of a 7 x 3.5 mm marquise center, framed by a handcrafted halo that amplifies its vintage-inspired drama with subtle brilliance.

Forged from warm 18K rose gold, the band is shaped for everyday grace—comfort fit with a low-profile setting that slips easily beneath gloves or stacks seamlessly alongside wedding bands. Each curve and prong is meticulously finished in our Williamsburg studio, where artisan hands ensure the halo’s pavé stones sit flush and secure, enhancing light play without excess height.

Our commitment to sustainability is reflected in the lab-grown diamond clarity and ethical sourcing behind every stone, offering a conscious alternative without compromise on sparkle or character.

This design suits those who appreciate a blend of architectural elegance and soft romance, especially flattering on slender fingers where the marquise shape elongates the hand. The semi-set nature allows you to select a center stone that resonates personally, ensuring a truly bespoke expression.
