Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that seems to dance with every movement. This semi-set halo engagement ring in 14K rose gold frames a 10 x 5 mm marquise center with delicate pavé accents, enhancing its vintage-inspired allure without overwhelming the stone’s elegant taper.

Handcrafted in our Williamsburg studio, the band’s warm rose hue is polished to a soft glow, complementing the marquise’s sharp points and brilliant facets. The low-profile halo setting balances sparkle with everyday wearability, while the comfort-fit shank ensures the ring settles gently against the finger.

Each lab-grown diamond is chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromise. The marquise shape’s elongating effect suits slender fingers and pairs beautifully with stackable bands or a wedding band designed to nestle closely.

Should you wish to adjust sizing, our in-studio experts provide precise resizing to maintain the ring’s integrity and comfort. Typical lead times allow for thoughtful customization, ensuring your vision is realized with care.
