Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the finger. This semi-set halo engagement ring in 10K yellow gold offers a luminous frame awaiting your choice of a 6 x 3 mm center stone, designed to amplify the diamond’s graceful drama.

Handcrafted in our Williamsburg studio, the band’s warm gold hue is polished to a soft glow, while the halo setting promises a gentle embrace that enhances brilliance without overwhelming. The low-profile design ensures comfort for daily wear, slipping easily beneath gloves or alongside stackable bands.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness, a quiet promise woven into every facet.

Ideal for those who appreciate a romantic silhouette with a modern edge, this ring suits slender to medium fingers, its shape elongating the hand with subtle elegance. The semi-set format invites personal choice, allowing you to select a center stone that resonates with your story.

Resizing is available to ensure a perfect fit, crafted with care to maintain the ring’s delicate balance.
