Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across the skin. This semi-set engagement ring invites you to select a 10 x 5 mm marquise stone, whose dramatic shape lends a refined, tapered elegance to the hand.

Crafted from warm 18K rose gold, the slender band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear. The solitaire setting is low-profile yet secure, allowing the diamond’s brilliance to take center stage without excess height or bulk. Each ring undergoes meticulous hand finishing and inspection to ensure a flawless surface and balanced feel.

Our diamonds are lab-grown, offering a clear, sustainable alternative that aligns with thoughtful craftsmanship and environmental mindfulness.

This ring suits those who appreciate a bold yet graceful statement—its narrow shape elongates the finger and pairs beautifully with stacking bands or a wedding ring. The low-profile setting slips easily under gloves or sleeves, making it a practical choice for daily life.

Should you wish to adjust sizing, our in-house team provides expert resizing to maintain the ring’s integrity and comfort.
