Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances with every movement. This semi-set engagement ring invites you to choose a center stone that echoes your unique story, framed by an 18K rose gold band that warms the skin with a subtle blush.

Crafted with precision in Williamsburg, the slender shank is designed for everyday grace—its low-profile setting ensures the diamond sits close to the finger, offering comfort without sacrificing presence. The smooth finish and balanced weight make it an effortless companion from morning light to evening glow.

Each lab-grown diamond option reflects a commitment to ethical clarity and sustainability, allowing brilliance without compromise. The marquise shape, with its tapered points and elongated form, visually lengthens the hand, lending an elegant, refined silhouette.

Ideal for those who appreciate a solitaire’s quiet strength and a ring that layers beautifully with wedding bands or stackable accents. Its gentle curve and modest height make it glove-friendly and unobtrusive for daily wear.

Should you need adjustments, resizing is available to ensure a seamless fit, crafted with the same care as the original design. Typical lead times reflect our bespoke approach, tailored to your chosen stone and finish.
