Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a square diamond, its facets unfolding like a miniature cityscape. This semi-set halo engagement ring in warm 10K rose gold offers a delicate frame for a 5.5 x 5.5 mm square center stone, inviting your choice to become the heart of its artisan-crafted embrace.

Hand-forged in our Williamsburg studio, the band’s subtle polish contrasts with the precise prong setting designed to secure and showcase the stone’s geometric clarity. The halo’s fine pavé work enhances brilliance without adding bulk, maintaining a low-profile silhouette that rests comfortably for everyday wear.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that reduce environmental impact while delivering exceptional clarity and sparkle.

Ideal for those who appreciate architectural lines and a refined yet approachable design, this ring pairs effortlessly with stacking bands or stands alone as a statement of modern romance. Its modest height ensures glove-friendly wear and ease of movement.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the ring’s integrity and finish.
