Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, casting a slender, luminous silhouette that seems to dance with every movement. This 14K rose gold halo engagement ring frames a 10 x 5 mm marquise stone, its pointed ends drawing the eye along a graceful, almost poetic line.

Handcrafted in Williamsburg, the ring’s halo setting enhances the diamond’s natural brilliance while maintaining a low-profile silhouette that rests comfortably against the finger. The warm blush of rose gold complements the stone’s fiery sparkle, polished to a satin finish that feels smooth to the touch and designed for everyday wear.

Each lab-grown diamond is ethically sourced, offering clarity and fire without compromise to the environment. The sustainable ethos behind this piece aligns with a modern commitment to responsible luxury.

Its slender band and subtle halo make this ring ideal for those who appreciate romantic detail without excess bulk—perfect for stacking or wearing solo. The low-profile setting ensures it slips easily beneath gloves or sleeves, marrying elegance with practicality.

Should you need a custom fit, resizing is available with care to preserve the ring’s delicate balance and finish. Typical lead times reflect the studio’s dedication to precision and quality.
