Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shimmer that seems to dance with every movement. This semi-set halo engagement ring in 18K rose gold frames a 7 x 3.5 mm marquise center, its pointed ends drawing the eye along a graceful arc.

Handcrafted in Williamsburg, the band’s warm rose hue complements the diamond’s fiery brilliance, while the halo setting enhances its lengthened shape without adding bulk. The low-profile design ensures a comfortable fit for daily wear, with smooth edges that rest gently against the finger.

Each piece is meticulously finished and inspected in-studio, reflecting a commitment to craftsmanship that honors both form and function. The lab-grown diamond at its heart offers clarity and sparkle with a lighter environmental footprint, aligning with a modern ethical sensibility.

Ideal for those who appreciate romantic geometry and subtle drama, this ring pairs beautifully with slender stacking bands or stands alone as a statement of refined taste. Its slender proportions suit a variety of hand sizes, offering a glove-friendly silhouette that moves effortlessly from morning light to evening glow.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks. Lead times are tailored to your design choices, with transparent communication throughout.
