Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of this marquise diamond, it traces a delicate arc that feels both intimate and expansive—like a whispered promise. Nestled in a three-stone setting, the 8 x 4 mm lab-grown marquise centers a trio of carefully matched stones, each secured in a low-profile platinum band that curves smoothly against the finger.

Crafted in Williamsburg, this ring balances refined engineering with subtle artistry: the platinum is hand-polished to a soft sheen, while the prongs hold the stones securely without interrupting their graceful line. Its comfort fit band allows for effortless daily wear, and the low profile ensures it slips easily under gloves or sleeves.

Each diamond is grown with precision in a controlled environment, offering clarity and brilliance without the environmental cost of traditional mining. This ethical approach complements the studio’s commitment to sustainable fine jewelry.

Designed for those who appreciate a blend of classic romance and modern minimalism, the marquise shape visually elongates the finger, while the three-stone arrangement symbolizes past, present, and future. It pairs beautifully with stacking bands or worn solo as a statement of quiet elegance.

Should you need a custom fit, resizing is available with care to maintain the ring’s structural integrity and finish. Typical lead times reflect the handcrafted nature of each piece.
