Lab-Grown Diamond Engagement Ring

Imagine the delicate silhouette of a marquise diamond catching the light as it elongates the finger with subtle drama. This semi-set halo engagement ring in 14K white gold frames a 6 x 3.5 mm marquise stone, inviting you to choose a center that reflects your story.

Crafted with precision in our Williamsburg studio, the halo setting enhances the stone’s pointed elegance while the polished white gold band offers a smooth, comfortable fit for everyday wear. The low-profile design keeps the ring close to the hand, making it ideal for stacking or pairing with a wedding band.

Each lab-grown diamond we work with embodies clarity and brilliance without compromise, reflecting a commitment to ethical jewelry that respects both people and planet.

This ring suits those who appreciate refined geometry and a touch of vintage romance, especially flattering on slender fingers where the marquise shape naturally elongates the hand. Its secure setting and balanced proportions ensure it wears gracefully through daily life.
