Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc that seems to stretch the hand with quiet elegance. This semi-set halo engagement ring in 18K white gold frames a 6 x 3.5 mm marquise center, its pointed ends softened by a circle of smaller stones that catch the eye without overwhelming.

Crafted with a low-profile setting, the band’s smooth finish ensures comfort for daily wear, while the halo’s subtle sparkle enhances the diamond’s natural brilliance. Each piece is meticulously polished and inspected in our Williamsburg studio, where precision meets thoughtful design.

Our diamonds are lab-grown, offering clarity and fire with a mindful approach to sustainability and ethical sourcing.

The slender shape and modest size suit those who appreciate refined geometry and a ring that layers effortlessly with other bands or stands alone with quiet confidence. Its low profile makes it glove-friendly and ideal for hands that favor understated grace.

Resizing is available to ensure a seamless fit, with careful attention to preserving the ring’s delicate balance.
