Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set halo engagement ring invites you to select a center stone that measures 12 by 6 millimeters, its distinctive shape offering a striking balance of drama and elegance.

Crafted in 14K white gold, the band is meticulously finished with a low-profile halo setting that frames the marquise with delicate pavé diamonds, enhancing brilliance without overwhelming wearability. The smooth comfort fit ensures the ring feels as natural as it looks, designed for everyday life in Williamsburg’s artisan spirit.

Each piece reflects a commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and sparkle with a reduced environmental footprint. This ring’s slender silhouette suits hands that appreciate refined geometry and works beautifully alongside stackable bands or as a singular statement.

Resizing is available to ensure a precise fit, and the semi-set design allows you to choose a marquise diamond that resonates personally, with expert guidance from our Brooklyn studio.
