Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that dances with every movement. This semi-set engagement ring frame in 10K yellow gold awaits your choice of a 10 x 5 mm marquise center, designed to showcase the stone’s tapered brilliance with subtle side accents that enhance its refined profile.

Crafted with a low-profile setting, the band sits close to the finger, offering a secure yet unobtrusive wear that suits daily life without catching or discomfort. The warm glow of yellow gold complements the marquise’s sharp geometry, while the delicate accents add a whisper of sparkle, all finished with meticulous hand polishing and inspection in our Williamsburg studio.

Each ring foundation embraces lab-grown diamonds for their clarity and ethical provenance, reflecting a commitment to sustainability without compromise on radiance.

The slender band and low profile make this mounting ideal for those seeking a ring that layers effortlessly with wedding bands or stackable styles, while the marquise shape elegantly elongates the finger’s natural line. Its secure prong setting ensures stability for active wearers who value both form and function.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to tailor the fit and finish.
