Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that seems to stretch beyond the hand. This semi-set solitaire invites you to select a center stone measuring 7 by 3.5 millimeters, its distinctive shape evoking a quiet drama and refined elegance.

Crafted in warm 14K yellow gold, the mounting balances a delicate profile with secure prongs that cradle the stone while allowing light to flood its facets. The band’s gentle curve and smooth finish ensure a comfort fit, designed to wear seamlessly every day without catching or crowding.

Each piece is thoughtfully made in our Williamsburg studio, where precision meets quiet artistry. The lab-grown diamond you choose will embody clarity and brilliance, reflecting a commitment to ethical jewelry that honors both beauty and sustainability.

Ideal for those who appreciate subtle statement and romantic geometry, this solitaire suits slender fingers and pairs effortlessly with stacking bands or a wedding ring. Its low-profile setting makes it glove-friendly and unobtrusive, perfect for daily life’s rhythms.
