Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set halo ring foundation in 14K white gold frames a 12 by 6 mm center stone with a whisper of brilliance, ready to cradle your chosen gem.

Crafted with a low-profile setting, the halo gently elevates the center without overwhelming, allowing daily wear with comfort and grace. The polished white gold band is subtly rounded for a comfort fit, designed to sit seamlessly alongside wedding bands or stackable rings.

Each piece is finished by hand in our Williamsburg studio, where meticulous inspection ensures the prongs align perfectly to secure your marquise diamond’s unique shape. The halo setting enhances the stone’s lengthened form, amplifying its vintage-inspired allure through modern craftsmanship.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and sparkle with a reduced environmental footprint.

This ring suits those who appreciate a blend of romantic geometry and everyday elegance—its slender profile fits comfortably under gloves and layers effortlessly with other bands.
