Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc—like a whispered promise unfolding. This semi-set halo engagement ring foundation in 10K white gold frames a 12 x 6 mm marquise center with delicate pavé accents, designed to amplify brilliance while maintaining a refined profile.

Crafted in our Williamsburg studio, the band’s smooth finish and low-profile setting ensure comfort for daily wear, slipping easily beneath gloves or alongside stackable bands. Each piece is meticulously inspected to balance sparkle with durability, honoring the quiet strength of the wearer.

Our diamonds are lab-grown, offering clarity and fire with a mindful footprint that reflects a commitment to sustainable luxury.

The marquise shape’s tapered points elongate the finger, ideal for those who appreciate a blend of vintage allure and modern geometry. This semi-set ring invites your choice of center stone, allowing a personalized connection to the design’s romantic framework.

Resizing is straightforward, handled with care to preserve the band’s integrity and finish.
