Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger as an 8 x 4 mm marquise diamond takes center stage, its tapered points framed by a delicate halo that catches light from every angle. This semi-set engagement ring foundation in 10K white gold offers a refined canvas for your chosen stone, crafted with precision in our Williamsburg studio.

The band’s smooth, low-profile silhouette ensures comfortable daily wear, while the halo setting enhances brilliance without adding bulk. Each curve and prong is hand-finished to a soft sheen, reflecting the artisan workshop’s commitment to meticulous detail and lasting durability.

Our lab-grown diamonds bring clarity and sparkle with a smaller environmental footprint, aligning with a modern ethical approach to fine jewelry.

Designed for those who appreciate a balance of classic shape and contemporary craftsmanship, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding ring. Its modest height slips easily beneath gloves or sleeves, making it a practical choice for everyday life.
