Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across the finger. This three-stone semi-set engagement ring in 14K rose gold frames a 9 x 4.5 mm marquise center with two gently tapering side stones, creating a quiet dance of light and shadow.

Handcrafted in Williamsburg, the band’s warm rose hue complements the diamond’s glassy, tapered elegance. The low-profile setting ensures the ring sits comfortably beneath daily wear, while the smooth finish and subtle curvature offer a natural fit that feels like a second skin.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to ethical jewelry that honors both beauty and sustainability without compromise.

Designed for those who appreciate romantic geometry and understated drama, this ring pairs effortlessly with stacking bands or stands alone as a statement of refined intention. Its shape elongates the finger, lending a graceful silhouette that suits slender and medium hand sizes alike.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as personal as the story it represents.
