Lab-Grown Diamond Engagement Ring

Imagine the moment your hand catches the light, the elongated marquise diamond tracing a delicate arc of fire and shadow. This semi-set solitaire invites you to choose a center stone that measures 9 by 4.5 millimeters, its pointed silhouette lending a graceful drama that elongates the finger.

Crafted in warm 18K yellow gold, the mounting balances classic warmth with a refined profile. The slender band tapers gently, designed for comfort and everyday wear, while the low-profile setting keeps the diamond close to the hand—ideal for stacking or pairing with a wedding band. Each piece is meticulously finished by hand in our Williamsburg studio, ensuring smooth edges and a polished surface that catches the eye without catching on fabric.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both the earth and your values. This ethical choice reflects a commitment to sustainability without compromise on beauty.

The ring’s silhouette suits those who appreciate subtle elegance with a hint of vintage allure, especially flattering on slender fingers or anyone seeking a statement that remains quietly sophisticated. The semi-set design means you can select a stone that perfectly matches your vision, with expert guidance available to help you find the ideal cut and clarity.

Resizing is straightforward, and the sturdy yet delicate band adapts well to adjustments without losing its refined shape.
