Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along a graceful arc that feels both intimate and expansive. This three-stone semi-set ring in 18K white gold offers a delicate balance of presence and subtlety, framing your chosen center stone with two gently curved side gems that enhance its natural brilliance.

Crafted with a low-profile setting, the band is polished to a soft sheen and shaped for comfort, allowing the ring to sit close to the finger without catching. Each prong is meticulously finished by hand in our Williamsburg studio, ensuring durability and a refined silhouette that complements daily wear.

Our commitment to ethical jewelry is reflected in the lab-grown diamond clarity and sustainability embedded in every piece, reducing environmental impact while celebrating beauty.

The slender 18K white gold band suits those who appreciate a refined, modern aesthetic with a romantic edge. Its low profile and smooth fit make it ideal for stacking or wearing alongside a wedding band, especially on slender to medium fingers where the marquise shape elongates the hand gracefully.

Should you wish to adjust sizing, our in-studio experts provide careful resizing to maintain the integrity of the setting without compromising comfort.
